A popular Mac blog is reporting that the iPhone may be headed to GSM carrier T-Mobile USA in the third quarter. Although T-Mobile is a GSM operator with a growing 3G network, its AWS deployment is not compatible with the radios found on the Apple smartphone which is currently compatible with AT&T's network. The source says that (s)he is 80 percent certain that the iPhone will hit T-Mobile in Q3.
For its part, T-Mobile parent company Deutsche Telekom has not been shy in aspiring to bring Apple's popular smarphone to its network by the end of the year.
With high demand of the iPhone and a msas rollout of the device in multiple countries globally, anything is possible, but it may not be likely if Apple has to retool the T-Mobile-specific device for 3G compatibility.
