AT&T 3G with Gevey Ultra
Hello,
I have an iphone 4 I bought in Japan:
Version: 4.3.3 (8J2)
Firmware: 04.10.1
I signed up for an AT&T account (with data plan) and got a sim card. Next, I bought a Gevey Ultra, cut my sim and did the manual unlock (dialing 112). It worked like a charm and now I can send texts and get AT&T signal, but without 3G.
The information from Gevey said that in order to get 3G, I needed to get the APN setting for cellular data from AT&T. I called AT&T and they said I should use data roaming instead of 3G. Is this true? If not, where can I find AT&T APN settings for my phone?
Thanks for your help,
John
