If i were to go to the apple store and buy an iphone today, would i be able unlock it and use it with my t mobile sim card. My buddy works at the apple store and he says a guy who works there has t mobile and also has the iphone working on t mobile. I am assume i would use ziphone. However does data services work on the iphone for t mobile. When i unlock the iphone if i do, can i just plug it into my mac, or do i have to worry about it turning into a brick??
