Ive had my 3g jail broken for a long time now, recently i switched to t-mobile. Everything was working fine until i had to leave my phone in the car when i went to visit the local court house. When i came out all the app icons changed back to the normal app icons that you see on a non jailbroken phone. Ive tried uninstalling the theme's and reinstalling them, re-booting, etc. This has never happened before, can anyone give me some insight on this problem?

Its an iphone 3g 16g
running version 3.1.2
unlocked/jailbroken using blackrain
