Apple has always been secretive, but after the iOS 5 panoramic camera mode was found hidden in code last week we didn’t expect any more suprises. Now (according to 9to5Mac) the same developer, Sonny Dickson, has found an auto-suggestion keyboard hidden in the iOS 5 code.
To activate (no jailbreak necessary) you simply need to use iBackupBot to tick Yes to Library/Prefernces/com.apple.keyboard.plist, and the Android style auto-correction is yours to enjoy.
Could the similarity to Android be the reason Apple bottled using it on initial release? Whatever the reason, it looks great and is yours to use now. Enjoy.
