Cannot Sync Unlocked IPHONE

[dgreat5000]

Ok, I have a unlocked IPHONE with a T-mobile SIM card in it. When I connect my IPHONE to the computer, the image viewer appears but nothing else. When I go to ITUNES, nothing happens.

Can anyone help me to figure out how to put music and videos on my unlocked iphone???

I just got the phone so I'm very new to this, I'd greatly appreciate it.

I have the same issue. I have always been able to Sync my iPhone which is modified. But just recently, I've noticed that when i plug it into my comp, the camera functions open but iTunes will not even recognize it. Is it an issue with my phone or iTunes? If i upgrade iTunes will that affect my modified iPhone also?
