Hello everyone, - Is it possible to use T-Mobile (Germany) iPhone 4 in the U.S. on the T-Mobile 3G Network? - Will it need to be hacked or unlocked to be able to use it? As you all know, AT&T iPhones only connect in EDGE on the T-Mobile network due to the use of a different frequency. I believe voice still connects in 3G, but data will connect in EDGE. Thanks!
