I have jailbroken my iphone 3G. I had firmware 3.0 and i upgraded it to 3.1.2 and than ran BlackRa1n and its JB now.

Only problem i now have is that a lot of my apps that are in the itunes library won't sync with my iphone. I get this pop-up:

The Progam isnt installed on the iphone because a unknow error occured (0xE8008001)

Can somebody help me please?

thnx in advance!!
