The '''iPad 2''' is a [[tablet computer|tablet]] designed, developed and marketed by [[Apple Inc.]] Compared to [[IPad (1st generation)|the first iPad]], as the second model in the [[iPad]] line, it gained a faster [[multi-core processor|dual core]] [[Apple A5|A5 processor]], a lighter build structure with a flat, rather than curved, back, and was the first iPad to feature VGA front-facing and [[720p]] rear-facing cameras designed for [[FaceTime]] video calling.

The device was available initially with three storage sizes – 16, 32 and 64 GB<ref>1 GB = 1 billion bytes</ref><ref name="AppleIPadSpecs"/> – and two varying connectivity options – [[Wi-Fi]] only or Wi-Fi and cellular. Each variation of the device is available with either a black or white front glass panel. However, upon the release of the [[iPad (3rd generation)|3rd generation iPad]] in March 2012, only the 16 GB variation remained available.

The product became available in March through May 2011.

The device received generally positive reception from various blogs and publications. Although it was praised for its hardware improvement, such as the new [[Apple A5]] chip, the software restriction on the iPad 2 and [[iOS]] in general drew criticism from various technology commentators.<ref name="engadgetreview1" /><ref name="Apple's Trend Away From Tinkering">{{cite web |url= http://apple.slashdot.org/story/10/01/31/1657233/Apples-Trend-Away-From-Tinkering |title= Apple's Trend Away From Tinkering |work= [[Slashdot]] |date= January 31, 2010 |access-date= April 15, 2012 |archive-date= February 8, 2010 |archive-url= https://web.archive.org/web/20100208164828/http://apple.slashdot.org/story/10/01/31/1657233/Apples-Trend-Away-From-Tinkering |url-status= live }}</ref> The device sold well in its first month of sales with 2.4–2.6 million units sold and 11.12 million units were sold in the third quarter of 2011.<ref>{{cite web | url=http://articles.businessinsider.com/2011-04-06/tech/30055408_1_ipad-apple-q2 | title=iPad 2 Sales Pegged At ~2.5 Million Units For March | publisher=Business Insider | date=April 6, 2011 | access-date=June 29, 2012 | author=Yarow, Jay | archive-url=https://web.archive.org/web/20121211101258/http://articles.businessinsider.com/2011-04-06/tech/30055408_1_ipad-apple-q2 | archive-date=December 11, 2012 | url-status=dead }}</ref><ref name="Q3 iPad Sales">{{cite web | url=http://ipadinsight.com/ipad-news/ipad-sales-numbers-for-q4-2011-announced-by-apple/ | title=iPad Sales Numbers for Q4 2011 Announced by Apple | publisher=iPad Insight | date=October 18, 2011 | access-date=June 29, 2012 | author=Jordon, Patrick | archive-date=March 5, 2021 | archive-url=https://web.archive.org/web/20210305221116/http://ipadinsight.com/ipad-news/ipad-sales-numbers-for-q4-2011-announced-by-apple/ | url-status=live }}</ref>

A popular product, with a lower screen resolution and performance than the two [[Retina display|Retina]] models that followed it but a lighter build and longer battery life, it remained in the Apple line-up as an entry-level iPad model for three years until March 2014, latterly with a silent upgrade to a [[die shrink|die-shrunk]] version of the A5 processor. Its basic design formed the core of the [[iPad Mini (1st generation)|first iPad Mini]], which had the same screen pixel count and similar features at a smaller size.

Originally shipped with [[iOS 4|iOS 4.3]], with the release of [[iOS 9]], the iPad 2 became the only device powered by the [[Apple A5]] to have received six major versions of iOS.

The April 29, 2011 release date for Japan was postponed due to the [[2011 Tōhoku earthquake and tsunami|earthquake and tsunami]] which struck the nation on March 11, 2011.

On September 19, 2012, almost a week after the announcement of the [[iPhone 5]], iOS 6 was released for numerous iOS devices, including the iPad 2 and [[iPhone 4S]].<ref name="iOS 6">{{cite web | url=http://www.slashgear.com/whats-new-in-ios-6-heres-the-changelog-19248506/ | title=What's new in iOS 6?

The software upgrade was downloadable as an over the air (OTA) update package and contains two hundred new features, including a mapping software designed by Apple dubbed [[Apple Maps]], a "Clock" app, which features a timer, stopwatch and alarm, and [[Facebook]] integration among other new features and tweaks.<ref name="iOS 6" />

The iPad 2 is compatible with [[iOS 7]], which was released on September 18, 2013.<ref>{{cite web|url=http://reviews.cnet.com/8301-19512_7-57588158-233/apple-devices-that-arent-invited-to-the-ios-7-party/|title=Apple devices that aren't invited to the iOS 7 party|publisher=CBS Interactive|work=CNET|access-date=June 23, 2013|archive-date=June 29, 2013|archive-url=https://web.archive.org/web/20130629051405/http://reviews.cnet.com/8301-19512_7-57588158-233/apple-devices-that-arent-invited-to-the-ios-7-party/|url-status=live}}</ref> However, some features are not available. For example, like the iPhone 4, the Notification Center and the Control Center use the transparent style instead of the translucent style in later iOS models. Also, [[AirDrop]], which was first released in iOS 7, was only supported by the iPad 4 or later.

The iPad 2 can run [[iOS 8]], which was released on September 17, 2014, making it the first iOS device to run five major versions of iOS (including iOS 4, 5, 6, 7, and 8).<ref>{{cite news|url=http://www.idownloadblog.com/2014/06/02/ios-8-is-compatible-with-iphone-4s-ipad-2-or-later/|title=iOS 8 is compatible with iPhone 4S, iPad 2 or later|publisher=iDownload Blog|date=June 2, 2014|access-date=June 2, 2014|archive-date=June 3, 2014|archive-url=https://web.archive.org/web/20140603125215/http://www.idownloadblog.com/2014/06/02/ios-8-is-compatible-with-iphone-4s-ipad-2-or-later/|url-status=live}}</ref> While the OS runs on the device, most of its new features do not work because of relatively aged hardware and therefore, its performance is limited. Users have also reported numerous problems after receiving the update including the accessibility features and battery-related issues. Many users speculated that the iPad 2 was going to be dropped from updating to iOS 8 along with the iPhone 4, the same process that happened with the iPhone 3GS and the iPod Touch (fourth generation) and earlier models, considering that the model was more than 3 years old.

It was confirmed on June 8, 2015, at Apple's [[WWDC]] that the iPad 2 would run [[iOS 9]], making it the first iOS device to run six major versions of iOS. As with previous releases, though, many headline features were unavailable on the iPad 2, including predictive [[Siri]], translucency effects, split-view, slide-over and [[picture-in-picture]] [[Computer multitasking|multitasking]] and the Health app.<ref>{{cite web|url=https://arstechnica.com/apple/2015/09/ios-9-on-the-ipad-2-not-worse-than-ios-8-but-missing-many-features/|title=iOS 9 on the iPad 2: Not worse than iOS 8, but missing many features|work=[[Ars Technica]]|author=Andrew Cunningham|date=September 16, 2015|access-date=June 14, 2017|archive-date=November 25, 2016|archive-url=https://web.archive.org/web/20161125071636/http://arstechnica.com/apple/2015/09/ios-9-on-the-ipad-2-not-worse-than-ios-8-but-missing-many-features/|url-status=live}}</ref><ref>{{cite web|url=https://arstechnica.com/apple/2015/09/ios-9-thoroughly-reviewed/2/|title=iOS 9, thoroughly reviewed|work=[[Ars Technica]]|author=Andrew Cunningham|date=September 16, 2015|access-date=June 14, 2017|archive-date=December 25, 2016|archive-url=https://web.archive.org/web/20161225204542/http://arstechnica.com/apple/2015/09/ios-9-thoroughly-reviewed/2/|url-status=live}}</ref> iOS 9 is said to feature performance improvements that may help the aging device function more smoothly, and initial tests suggest that it did not significantly impact available space. Other A5-based devices will also run iOS 9 including the iPhone 4S (five major iOS versions), the iPad Mini (four major iOS versions) and [[iPod Touch (5th generation)|iPod Touch 5G]] (four major iOS versions).

On June 13, 2016, with the announcement of [[iOS 10]], Apple dropped support for the iPad 2 because of its hardware and performance issues, making iOS 9.3.5 (Wi-Fi) or iOS 9.3.6 (Wi-Fi + Cellular) the final version that will run on the device.<ref>{{Cite web|url=https://www.apple.com/ios/ios10-preview/|title=iOS 10 – Apple|access-date=September 9, 2017|archive-date=September 2, 2016|archive-url=https://web.archive.org/web/20160902231258/http://www.apple.com/ios/ios10-preview/|url-status=live}}</ref>

===="Broadpwn" exploit vulnerability====
The iPad 2 is one of many computers, tablets, and mobile devices susceptible to the [[IOS 9#"Broadpwn" Wi-Fi vulnerability|"Broadpwn"]] exploit, which was publicized in July 2017.<ref>{{cite web |first=Nitay |last=Artenstein |title=Broadpwn: Remotely Compromising Android and iOS via a Bug in Broadcom's Wi-Fi Chipsets |date=2017-07-26 |publisher=Exodus Intelligence |url=https://blog.exodusintel.com/author/exodusvrt/ |access-date=August 3, 2017 |archive-date=August 4, 2017 |archive-url=https://web.archive.org/web/20170804013640/https://blog.exodusintel.com/author/exodusvrt/ |url-status=live }}</ref> Apple quickly released an update for [[iOS 10]] to fix the problem, but a fix was never released for [[iOS 9]] or earlier versions of iOS. As a result, older Apple devices incompatible with iOS 10, including the iPad 2, were left vulnerable indefinitely. This has raised concerns of potentially widespread attacks using the exploit, particularly in locations of concentrated iPad 2 deployment, such as certain primary and secondary schools.<ref>{{cite web |first=Andrew |last=Walters |title=Thousands of iPad 2 tablets in schools just became ticking timebombs |url=https://www.sirius.co.nz/thousands-of-ipad-2-tablets-are-ticking-timebombs/ |publisher=Sirius Information Services [New Zealand] |date=2017-08-01 |url-status=dead |archive-url=https://web.archive.org/web/20190119182158/https://www.sirius.co.nz/thousands-of-ipad-2-tablets-are-ticking-timebombs/ |archive-date=2019-01-19 }}</ref>

====2019 GPS rollover update====

On July 22, 2019, Apple released iOS 9.3.6 for the CDMA model of the iPad 2 to fix issues caused by the [[GPS Week Number Rollover|GPS week number rollover]]. The issues would impact accuracy of GPS location and set the device's date and time to an incorrect value,<ref>{{cite web|url=https://support.apple.com/en-us/HT208010#936|title=About iOS 9 Updates|publisher=Apple|access-date=January 4, 2020|archive-date=July 22, 2019|archive-url=https://web.archive.org/web/20190722180845/https://support.apple.com/en-us/HT208010#936|url-status=live}}</ref> preventing connection to [[HTTPS]] servers and, consequently, Apple's servers for activation, iCloud and the iTunes and App stores. The WiFi model and the GSM model are not affected by the rollover as the WiFi model lacks a GPS chipset and the GSM model uses a different chipset.

3G versions of the iPad 2 offer [[CDMA2000]] support for customers using the device on a CDMA network or [[GSM]]/[[UMTS]] support for customers using the device on a GSM/UMTS network. The iPad Wi-Fi + 3G model includes an [[A-GPS]] receiver for tracking the user's location given permission. Also, the iPad 2 3G model includes a plastic cap-like band at the top on the back for the 3G antenna. The metallic grille for the microphone is replaced with a matching plastic black grille on the 3G model.<ref>{{cite web | url=http://www.anandtech.com/show/4225/the-ipad-2-review/11 | title=The Apple iPad 2 Review | publisher=[[Anandtech]] | date=March 19, 2011 | access-date=June 30, 2012 | author=Klug, Brian | archive-date=June 14, 2012 | archive-url=https://web.archive.org/web/20120614084436/http://www.anandtech.com/show/4225/the-ipad-2-review/11 | url-status=live }}</ref>
GSM models of iPad 2 use a [[Subscriber identity module|SIM]] card while CDMA models use an [[Electronic serial number|ESN]] to connect to the cellular network.

===Accessories===
{{main|List of iPad accessories}}

The [[IPad accessories#Smart Cover|Smart Cover]], first introduced with the iPad 2, is a screen protector that magnetically attaches to the face of the iPad. The cover has three folds which allow it to convert into a stand, which is also held together by magnets.<ref name=SmartCoverTeardown>{{cite web|title=iPad 2 Smart Cover Teardown|date=March 13, 2011 |url=https://www.ifixit.com/Teardown/iPad-2-Smart-Cover-Teardown/5089/1|publisher=iFixit|access-date=May 12, 2012|archive-date=March 17, 2011|archive-url=https://web.archive.org/web/20110317093925/http://www.ifixit.com/Teardown/iPad-2-Smart-Cover-Teardown/5089/1|url-status=live}}</ref> While original iPad owners could purchase a black case that included a similarly folding cover, the Smart Cover is meant to be more minimal, easily detachable, and protects only the screen. Smart Covers have a [[microfiber]] bottom that cleans the front of the iPad, and wakes up the iPad when the cover is removed.

==Reception==
The iPad 2 received generally positive reviews, praising its Apple A5 processor and 720p camera. [[Joshua Topolsky]] of [[Engadget]] said that "for those of you who haven't yet made the leap, feel free to take a deep breath and dive in – the iPad 2 is as good as it gets right now. And it's really quite good."<ref name="engadgetreview1">{{cite web | url=https://www.engadget.com/2011/03/09/ipad-2-review/ | title=iPad 2 review | publisher=[[AOL]] | work=[[Engadget]] | date=March 9, 2011 | access-date=April 18, 2012 | author=Topolsky, Joshua | author-link=Joshua Topolsky | archive-date=April 19, 2012 | archive-url=https://web.archive.org/web/20120419163835/http://www.engadget.com/2011/03/09/ipad-2-review | url-status=live }}</ref> [[Jason Snell (writer)|Jason Snell]] of ''[[Macworld]]'' said the following:

<blockquote>
"Though the iPad 2 is an improvement on the original iPad in numerous ways, it's still an evolutionary product, not a revolutionary one. If you're happy with your current iPad, there's no reason to dump it just because there's a shinier, newer one. (This is not to say that millions of people won't do just that. I mean: shiny!) If you've invested in iPad accessories such as a dock or case, keep in mind that you probably won't be able to use them with the new iPad."<ref name="macworldreview">{{cite web | url=https://www.macworld.com/article/1158439/ipad2.html | title=Review: The iPad 2 | publisher=[[Mac Publishing]] | work=[[Macworld]] | date=March 9, 2011 | access-date=April 19, 2012 | author=Snell, Jason | author-link=Jason Snell (writer) | archive-date=April 21, 2012 | archive-url=https://web.archive.org/web/20120421005936/http://www.macworld.com/article/1158439/ipad2.html | url-status=live }}</ref>

===Criticism===
The closed and proprietary nature of iOS has garnered criticism, particularly by [[digital rights]] advocates such as the [[Electronic Frontier Foundation]], computer engineer and activist [[Brewster Kahle]], Internet-law specialist [[Jonathan Zittrain]], and the [[Free Software Foundation]] who protested the iPad's introductory event and have targeted the iPad with their "[[Defective by Design]]" campaign.<ref>{{cite web |url= http://www.defectivebydesign.org/ipad |title= iPad DRM endangers our rights |date= February 3, 2012 |access-date= April 19, 2012 |publisher= [[Defective by Design]] |archive-date= April 12, 2012 |archive-url= https://web.archive.org/web/20120412122641/http://www.defectivebydesign.org/ipad |url-status= live }}</ref><ref>{{cite web |url= https://arstechnica.com/tech-policy/news/2010/01/protestors-ipad-is-nothing-more-than-a-golden-calf-of-drm.ars |title= Protestors: iPad is nothing more than a golden calf of DRM |author= Nate Anderson |date= January 27, 2010 |access-date= April 15, 2012 |archive-date= January 19, 2012 |archive-url= https://web.archive.org/web/20120119210900/http://arstechnica.com/tech-policy/news/2010/01/protestors-ipad-is-nothing-more-than-a-golden-calf-of-drm.ars |url-status= live }}</ref><ref>{{cite web |url= http://thedianerehmshow.org/shows/2010-02-03/mobile-devices-and-next-computing-revolution-0 |title= Mobile Devices and the Next Computing Revolution |date= February 3, 2010 |access-date= April 15, 2012 |archive-date= December 1, 2010 |archive-url= https://web.archive.org/web/20101201053215/http://thedianerehmshow.org/shows/2010-02-03/mobile-devices-and-next-computing-revolution-0 |url-status= live }}</ref><ref>{{cite news |url= https://www.theguardian.com/technology/2010/feb/01/apple-ipad-choke-innovation |title= Apple iPad will choke innovation, say open internet advocates |work= [[The Guardian]] |date= February 1, 2010 |author= Bobbie Johnson |access-date= April 15, 2012 |archive-date= March 16, 2014 |archive-url= https://web.archive.org/web/20140316141036/http://www.theguardian.com/technology/2010/feb/01/apple-ipad-choke-innovation |url-status= live }}</ref> Competitor [[Microsoft]], via a PR spokesman, has also criticized Apple's control over its platform.<ref>{{cite web | url = http://technologizer.com/2010/01/28/microsoft-ipads-closed-platfor-is-humorous/ | title = Microsoft PR spokesman condemns iPad for being "locked down" | author = Worthington, David | work = Technologizer | date = January 28, 2010 | access-date = April 19, 2012 | archive-date = March 5, 2012 | archive-url = https://web.archive.org/web/20120305021357/http://technologizer.com/2010/01/28/microsoft-ipads-closed-platfor-is-humorous/ | url-status = live }}</ref>

===Technical problems===
At issue are restrictions imposed by the design of iOS, namely [[Digital rights management|DRM]] intended to lock purchased media to Apple's platform, the development model (requiring a yearly subscription to distribute apps developed for the iOS), the centralized approval process for apps, as well as Apple's general control and lockdown of the platform itself. Particularly at issue is the ability for Apple to remotely disable or delete apps at will. Some in the tech community have expressed concern that the locked-down iOS represents a growing trend in Apple's approach to computing, particularly Apple's shift away from machines that hobbyists can "tinker with" and note the potential for such restrictions to stifle software innovation.<ref name="Apple's Trend Away From Tinkering"/><ref>{{cite video| url = https://www.youtube.com/watch?v=JDrJd7GkkNA| title = Campus Party Brasil 2011&nbsp;– Geek Pride e Wozniak| people = [[Steve Wozniak]] (Interviewee)| date = January 22, 2011| publisher = Fragoso, Victor| access-date = March 7, 2011| archive-date = May 12, 2011| archive-url = https://web.archive.org/web/20110512222742/http://www.youtube.com/watch?v=JDrJd7GkkNA| url-status = live}}</ref>
