Hello. I got a locked iPhone 4 and i'm still having doubts about buying the GeveySIM, the price doesn't really bother me. What does really bother me is that if the 3G will work or not... One of the main parts I need to have it unlocked now is the Cell phone internet, And on the GeveySIM's site they say some some carriers may not work with the 3G. No one have tested it yet where I live. So I was wondering, what is needed to have an EDGE internet? I mean what's EDGE And what's 3G? is EDGE more expensive? How does it work? Can I still have internet network with EDGE? Thank you very much!
