Quadband GSM, Steve Jobs said, and you could hear the hiss of excitement as eager T-Mobile USA customers suddenly wondered if they'd be able to take advantage of the iPhone 4. Unfortunately, a quick glance at the freshly posted spec sheet confirms their hopes are in vain: the iPhone 4 supports 850, 900, 1900 and 2100 MHz UMTS/HSDPA/HSUPA, not the 1700/2100 T-Mobile USA requires.
What does this mean? Basically, when the first iPhone 4 unlock hack is released - and we don't expect it to take long after the smartphone hits shelves on June 24th - T-Mobile USA subscribers will still only be able to take advantage of quadband GSM/EDGE, just like on the current, triband iPhone 3GS.
