If Sprint iPhone 5 speculations are to be believed, along with previous reports of iPhone test units running on T-Mobile, we could end the wait and see Apple’s devices on all four major US network carriers this year.
While also a GSM/HSPA/HSPA+ network, T-Mobile on iPhone 5 would have to support on AWS (Advanced Wireless Services, which powered in the 1700 and 2100 bands), a very different set of 3G frequencies than AT&T. Whether or not Apple could merge all those frequencies into one GSM iPhone 5 antenna array, we just don’t have to point out a single CDMA/GSM “world phone” that could work on Verizon, Sprint, AT&T, and T-Mobile, although it is the question.
AT&T is also into the operation of trying to snap T-Mobile US, in part to use their AWS spectrum to increase AT&T’s own LTE 4G rollout.
How, if at all, that would affect an AWS iPhone 4 is still remains to be seen. Meanwhile, Canadian carriers Moblicity, Wind, and Videotron use the same 3G bands as T-Mobile US, so an AWS-compatible iPhone 5 would still have some not that open international appeal.
