This does work but do this...

1. Install Any Cracked BeejiveIM
2. Copy this file from a free apptore app "iTunesMetadata.plist" without quotes
2. SSH into your iPod
3. Go to var/mobile/Applications/xxxxxxxxxxxxxxxxxxxxxxx

X=Look in each folder untill you found BeejiveIM.app

7. Copy "iTunesMetadata.plist" from the free app.
8. Place it in the same folder BeejiveIM.app is in and not the Beejive.app folder itself.
9.Done!

Is should work for all Appstore Apps
