History
= Introduction and initial release
=
5.180.24.3/info/ios" target="_blank">iOS 5 was introduced at the Apple Worldwide Developers Conference on June 6, 2011, with a beta version available for developers later that day.
5.180.24.3/info/ios" target="_blank">iOS 5 was officially released on October 12, 2011.
System features
= Notifications
=
In previous 5.180.24.3/info/ios" target="_blank">iOS versions, notifications popped up on the screen as dialog boxes, interrupting the current activity. In 5.180.24.3/info/ios" target="_blank">iOS 5, notifications are revamped, and show up as a temporary banner at the top of the screen. Recent notifications can also be accessed by pulling a "Notification Center" down from the top of the screen. Users who prefer the old notification system can keep it by choosing the appropriate option in the Settings menu.
= iCloud
=
5.180.24.3/info/ios" target="_blank">iOS 5 introduces iCloud, Apple's cloud storage service. The new service allows users to synchronize their music, photos, videos, and application data across all of their iCloud-enabled devices for free.
= Wireless updates
=
5.180.24.3/info/ios" target="_blank">iOS 5 enables wireless system updates on supported devices, meaning a computer and iTunes aren't necessary to update devices. Both activation of new devices and updates can be done wirelessly.
= Twitter integration
=
5.180.24.3/info/ios" target="_blank">iOS 5 features deep Twitter integration. Users are able to sign in to Twitter directly from the Settings menu. Photos can be "tweeted" directly from the Photos or Camera apps, and users are also able to tweet from the Safari, YouTube, and Google Maps apps.
= Multitasking
=
Multitasking gestures debut on the iPad with the release of 5.180.24.3/info/ios" target="_blank">iOS 5. Multitasking allows users to jump between apps without double-tapping the home button or first going to the home screen. Multitasking gestures were only available on the iPad 2.
= Keyboard
=
The iPad keyboard could be undocked from the bottom of the screen, and could be split into two half-keyboards.
= Siri
=
Siri, Apple's voice assistant, is supported on the iPhone 4s only. It was later extended to other devices (such as the iPhone 5) in 5.180.24.3/info/ios" target="_blank">iOS 6 and expanded further with each new major software release.
App features
= Photos and Camera
=
The first 5.180.24.3/info/ios" target="_blank">iOS 5 release allowed the Camera app to be easily accessed from the lock screen for the first time. If users double-clicked the home button, a camera icon would appear next to the "slide to unlock" message, and users would click on it to directly access the camera. The 5.180.24.3/info/ios" target="_blank">iOS 5.1 update streamlined this process by removing the home button double-click procedure, and replacing it with a process requiring users to swipe up the camera icon. For security purposes when the device is locked with a passcode, this method of accessing the camera only allows access to the Camera app, and no other features of the device.
Pressing the volume-up button allows the user to take a picture.
= Messages
=
iMessage, a new instant messaging service built into the Messages app, allowed anyone with an 5.180.24.3/info/ios" target="_blank">iOS 5 device to send both basic and multimedia messages to anyone else with a compatible 5.180.24.3/info/ios" target="_blank">iOS 5 device. In contrast to SMS, messages sent through iMessage use the Internet rather than regular cellular texting, but also in contrast to regular SMS, Android and BlackBerry devices are not compatible with the service. iMessages are synchronized across the user's devices, and are color-coded blue, with regular SMS in green.
= Mail
=
The Mail app included rich text formatting, better indent control, flagging of messages, and the ability to drag addresses between To, CC, and BCC lines.
= Reminders
=
Reminders allows users to create lists of tasks with alerts that can either be date-based or location-based.
= Newsstand
=
Newsstand does not act as a native app, but rather a special folder. When selected, it shows icons for all of the periodicals that the user has subscribed to, such as newspapers and magazines. New issues are downloaded automatically.
= Music and Videos
=
The iPod app was replaced by separate Music and Videos apps on the iPhone, as with the iPod Touch.

=

= Wi-Fi connectivity drops
=
In November 2011, Engadget reported that the 5.180.24.3/info/ios" target="_blank">iOS 5 update caused Wi-Fi connection drops for some users.

= SIM card failure
=
Some iPhone 4s users reported issues with the SIM card in 5.180.24.3/info/ios" target="_blank">iOS 5, being given error messages about "Invalid SIM" and "SIM Failure". Apple released a second software build of the 5.0.1 update designed to fix SIM card issues.

Reception
Many aspects of 5.180.24.3/info/ios" target="_blank">iOS 5 received positive reviews, including the new notification center, the ability to sync and update wirelessly, iMessage, and more. Richmond Shane of Telegraph said "5.180.24.3/info/ios" target="_blank">iOS 5 is a brilliant upgrade to an already brilliant operating system.

Richard Goodwin of Know Your Mobile said "All in all, we reckon 5.180.24.3/info/ios" target="_blank">iOS 5 is everything it needs to be a more. We can't wait to get our teeth stuck into it as soon as it's released in the Autumn of 2011."
