It would have left effectively two almost monopolies, in the two major spectrums in the United States: Verizon CDMA; AT&T for GSM. I think that was the big thing, now you have options Sprint/Verizon and T-Mobile/AT&T.
Of course what most have failed to note is T-Mobile isnt going to make it. The speculation was they dont see the end of 2012, but the cash infusion from the failed AT&T bid might sustain them through 2013, when theyll declare bankruptcy and put their assets up for sale, where AT&T will be able to buy them, probably at a discounted rate though Verizon might decide to bid just to make it expensive.
T-Mobile USA isn't going broke, are they?
Deutsche Telekom owns them anyway...
T-Mobile USA can't be doing as bad as Sprint... Sprint hasn't made money in years!
