So, I first want to say I know that any iPhone will not work on T-Mobile's 3G/4G network, but I do want to ask this question. I heard a rumor, or maybe it's actually factual, that AT&T and T-Mobile are going to eventually allow customers to roam on each other's networks. If AT&T was to somehow either get Apple to unlock the baseband and cellular antennas of iPhones to include T-Mobile's AWS band (1700 MHz) (Highly unlikely, and I'm not sure this would be doable on anything other than the iPhone 4S, because the modem in that theoretically supports the AWS band, but I'm not sure about the 4 or 3GS), or T-Mobile started reframing some of their network capacity to 1900 MHz in order to allow all AT&T phones to roam on their 3G network (more likely), could the iPhone 4S actually be called 4G, because it is on T-Mobile's 21 Mbps/42 Mbps "4G" network? Also, if an iPhone 4S is on T-Mobile's 3G/4G network, and in an area that is 42 Mbps capable, could we actually start seeing the limits of the modem (14.4 Mbps download, 5.76 Mbps upload), actually be the reason that you can't have faster network speeds? I was looking at the speedtest results for phones equipped for, and in areas with the 42 Mbps speed, and they seem to be anywhere from 11, all the way up to 19. If an iPhone 4S was on this network, would we actually see speeds this high, or would we actually see caps on internet speed, or simply not as high as the phones that T-Mobile sells?
