Just wanted to share, attached is an old app based on shell script, i tested it and made a bit of modification here and there on the script and its permissions and now it works perfectly. Anything you got runnin' in 1.1.x that are based on shell script seems will work fine in 2.0 as well.
The app purpose is to swap your camera roll, anyone can modify this to swapPhotoLibrary or swapiTunesLibrary if they want. So if anyone find it useful, just upload it to Cydia
otherwise, just unzip and sftp it to the usual /Applications directory.
cheers,
