I am moving to Europe and want to know if I will be able to use my iPhone with a European (Germany specific) cell carrier? I don't want to use AT&T and pay their roaming charges for the next two years. Thanks for your help. I've got an iPhone 3G but have upgraded it to the 3.1 system. The contract with At&t doesn't matter as I'm in the military and can get out of it with orders. If I JB/unlock it can I still connect it to my computer?
