jailbroke 3g with app problems

[damhandstand]

i used winpwn2.5 to jailbreak my 3g with the 2.02 firmware. the jailbreaking worked fine and cydia and installer work fine. but all the application store apps are no longer working. they will download, and open up and show the title screen. but after that they will automatically close.

what do i need to do to fix this?

assuming you have synched with itunes, just delete them off the iphone (hold down until they start wiggling, then hit the X). Then synch with itunes and it'll reinstall them. I had the exact same issue and this fixed it.
