<p>iOS 5 is the <a href="/facts/IOS_version_history/4CILLmV7">fifth major release</a> of the <a href="/facts/IOS/mK5cggH5">iOS</a> <a href="/facts/Mobile_operating_system/wysBVca1">mobile operating system</a> developed by <a href="/facts/Apple_Inc./oTJYta3k">Apple Inc.</a>, being the successor to <a href="/facts/IOS_4/kLchkK4Y">iOS 4</a>. It was announced at the company's <a href="/facts/Worldwide_Developers_Conference/hEjVWkoo">Worldwide Developers Conference</a> on June 6, 2011, and was released on October 12, 2011. It was succeeded by <a href="/facts/IOS_6/xKr1nM6P">iOS 6</a> on September 19, 2012. </p><p>iOS 5 revamped notifications, adding temporary banners that appear at the top of the screen and introducing the <a href="/facts/Notification_Center/Ez3asjLp">Notification Center</a>, a central location for all recent notifications. iOS 5 also added <a href="/facts/ICloud/AUcIyg4L">iCloud</a>, Apple's <a href="/facts/Cloud_storage_service/AWz9wQt8">cloud storage service</a> for synchronization of content and data across iCloud-enabled devices, and <a href="/facts/IMessage/0oMKq4Xq">iMessage</a>, Apple's <a href="/facts/Instant_messaging/8lwwDyjK">instant messaging</a> service. For the first time, software updates could be installed wirelessly, without requiring a computer and <a href="/facts/ITunes/pdXPE33T">iTunes</a>. iOS 5 also featured deep integration with <a href="/facts/Twitter/VWwDNGUm">Twitter</a>, introduced multitasking gestures on <a href="/facts/IPad/Ql67x0Dw">iPads</a>, and added an easily accessible camera shortcut from the lock screen. </p><p>iOS 5 was the subject of criticism for <a href="/facts/IPhone_4s/Wu68J786">iPhone 4s</a> users, as the initial release had poor battery life, failures of <a href="/facts/SIM_card/NUeSqoG1">SIM cards</a>, and echoes during phone calls. These problems were fixed in subsequent releases. </p><p>iOS 5 is the last version of iOS that supports the <a href="/facts/IPod_Touch_(3rd_generation)/PRJabx51">third-generation iPod Touch</a> and <a href="/facts/IPad_(1st_generation)/FCH0AXW9">first-generation iPad</a>. </p>
