Hello! I could not find an answer on the internet but anyways that is beyond the point. I have a Iphone 2g since it first launched, and I am currently living in Shanghai. Well, I am very interested in the Iphone 4g and I am not sure if the iphone itself is connected to a provider right out of the box? Since, AT&T is not existent in China, I was wondering if I can just plug in a sim card or subscribe to another provider in China instead? Thanks!!
