App Crashes Help!! (2.1)

[mikethekobra]

I recently pwned my phone and installed customize from cydia which does not work it loads up and then crashes and goes back to the home screen. Also i did the ipa hack and installed tetris and it worked for a day but now it does the same as customize. I have 2.1 firmware tia
