Take my advice - A SGS2 user, bought an unlocked iPhone 5 after T-mobile announced Minneapolis is refarmed. Lousy coverage. I have Edge most of the time, and when you do see 3G on your iPhone and you enter a building it switches back to Edge. I frequently have seen no service on my iPhone 5, which I never see on the T-mobile HSPA+ network. I switched back to SGS2. The refarmed 1900 Mhz 3G compatible with iPhones is worse than Sprint. You get what you pay for. And there is more..! T-mobile while claiming 120 million US population covered in 40 cities, it refuses to put 3G coverage maps!
