I have a 2G iphone that is jailbroken but ever since Ive upgraded to iTunes v8.2.1, when I try and upload apps to the phone, it fails each time. I try and load the same apps to my 3G iphone and they work perfectly??

The error message is below

"The application "contacts3d" was not installed on the iPhone "2g iPhone" because an unknown error occurred (0xE8008001)"

Does anyone have any suggestions??
