Aight! I Give Up!
Ok, so I love APTBackup, but forgot to run the backup portion prior to a recent restore and re-JB, so now I can't find all my old aps. RATS!
ANyway I'm drawing a blank on the name of one I used heavily. It was a Pic Vault that had heavy encryption, a built in web server for moving stuff back and forth, and the best feature was that it allowed you to pick any icon and rename it how youn wanted. It also had a stealth mode. You open the app, and it presented you with a notepad page. This is where you entered the passcode which was a series of touches in different areas of the screen. If you got it wrong or if the user didn't know what to do, after a set ammount of time it would "crash" back to the spring board.
It has a few more features too. If anyone can tell me the name I'll give you all my internetz for a month!!
