Hey guys, So i decided to follow the advice from my fellow peers on mac rumors and went out and bought a gevey sim card to use my iphone 4 on t-mobile. Everything seems to be working great. I can make and receive calls, send and receive text messages but!!!, and there is always a "but", I can't send and receive picture messages, I can't use facetime, and worse of all, I don't have 3g. I am on the edge network. I was told that If I had a jailbroken device I can purchase Mi-time, which works with fact-time. But in terms of the sending and receiving mms messages and using the 3g network am I screwed? please help! thanks guys.
