Hello! I have an iphone 4 running on the gophone unlimited call and text with 200mb of data plan working perfect. I haven't even jailbroken the iphone yet. My iphone is running ios 4.1 with baseband 1.59.0. Is anyone running gophone with the new ios 4.2.1? I know since is att there is no need to unlock but i just need to double check before i upgrade my phone. Thanks!
