Apple's updated iPhone 5 for T-Mobile goes through FCC testing
 

An iPhone native to T-Mobile USA has been the stuff of legend for so long that we still have a hard time believing it's real, even after the carrier confirmed it in no uncertain terms. We're a little more credulous now that Apple has run the iPhone 5 through some class permission changes at the FCC. True to the words of Apple and T-Mobile, the updated A1428 is now clear to use 42Mbps HSPA+ data on the AWS frequencies that the UnCarrier uses (along with smaller Canadian providers, we'd add). The refreshed iPhone doesn't have any surprises lurking underneath -- the LTE was already in place -- although that in itself isn't surprising. It's a mid-cycle tweak meant chiefly to expand Apple's market reach, and we wouldn't expect much more iPhone-related FCC action for awhile.
