How to enable iOS 5's hidden panorama camera

Before we go over all the details, it's good to note that changing files like we are going to is never a great idea unless you are comfortable in troubleshooting any issues, should things go wrong.
With the disclaimer out of the way, let's get started.

1. Back up your device in iTunes. You cannot use an iCloud backup.
2. Download and install iBackupBot.
 
3. Open iBackupBot after it's installed. The backup you just created should be visible. Open the backup to have access to a list of system files. Scroll through the list and find the file titled: Library/Preferences/com.apple.mobileslideshow.plist. Double-click to open the file. If you are presented with a registration dialog for iBackupBot, press Cancel.

4. Scroll to the bottom of the file. You should see an entry:

   <key>DiskSpaceWasLow</key>
   <false/>

   Directly below that, enter the following:

   <key>EnableFirebreak</key>
   <string>YES</string>

   
   Save the file and close it.
 
5. Restore your device from within iBackupBot by clicking on the Restore button highlighted above. Don't worry, you won't lose any apps or settings.
 
6. After your device is restored, open the Camera app and tap on the Options button. You should now see a Panorama button.
 
7. Tapping on the Panorama button will present you with a new UI for taking a panoramic photo. Follow the onscreen instructions to take a panoramic photo.

It's clear why this feature hasn't been released as of yet. Even with the steadiest of hands, the photos we attempted to take came out pretty choppy. The feature should be available on any device with a gyroscope, however, we ran into issues testing on an iPad 2. Your results may vary.
