Hi, I bought an iPhone 5 last week from bangkok. Its made in Korea, since it has KCC-xxx-xxxx coding in the back. Asked people at Apple forums and they said, its perfectly legit as well and I had tested the Apple serial number too. All good. But one thing. Im not able to UPDATE or RESTORE to iOS7 Beta 2 or 4 or 5 or 6. It keeps on showing me error. Has anyone tried doing this ?
