I've fond a few interesting articles on the internet, how to enable the new autocorrect feature and a new panorama feature on iOS. Without a jailbreak!
As these are not announced by Apple yet, expect some bugs and not so clean interface design.
First, make sure u have iOS 5.0.1 on your phone (will work with 5.0 as well).
Make a backup with itunes. If u usually use iCloud, just rightclick on the iPhone in iTunes and hit the backup button.
Download the following Software: iBackupBot (http://www.icopybot.com/itunes-backup-manager.htm) available for Mac and PC.
Fire up iBackupBot. Look for your latest Backup and open it.
New Autocorrect:
Go to Library/Preferences/com.apple.keyboard.plist and open it. If you have the unregistered version of iBackupBot just hit cancel, the file opens anyway.
Add in the following code: KeyboardAutocorrectionLists YES
Mine now looks like this:
Save and close.
Panorama Mode:
Find the file /Library/Preferences/com.apple.mobileslideshow.plist
Look for the key:
Add below this key:
Save and close.
Finish up:
Klick in iBackupBot on the main menu on the iPhone with the blue arrow.
