Today i have installed iOS 5.1 on my Apple iPad 2. This update is 206 Mb in size. I used direct update on my iPad using Wifi in my office.
iOS 5.1 brings a number of improvements and bug fixes, including the previously-announced Japanese language support for Siri, a redesigned camera app for iPad, the ability to delete individual photos from Photo Stream and, somewhat curiously, an “updated AT&T network indicator.” What’s more, as previously rumored, the camera shortcut is now also always visible on the lock screen for iPhone and iPod touch users.
