I'm wondering if anyone has any experience or advice using an iPhone 4 while travelling in China. Currently my phone is on the Rogers network in Canada (not unlocked or jailbroken); Version 4.2.1 and baseband 3.10.01. I will be living in Beijing for about a year, and was hoping to use my iPhone 4 out there.
I'm looking into maybe getting the Gevey Sim Pro for the phone to unlock it, as I understand that is one of the ways to unlock this version. I'm open to other suggestions though!
