Hi I am New to this, so take it easy on me.

I have a problem with my Iphone 3g 2.0.1 that is ulocked and jailbroken for T-mobile, When I connect it to my computer, the computer recognizes it as if it was a camera, and when I open Itunes it showes up and it trys to connect to the appstore and but it never connects. So now there is no way that I can go threw the media on my iphone and remove some. I can only add media but, I cant see whats in the phone either, please help.
