Fat lot of nonsense. For one thing, the new version of the iPhone does support MMS, so Apple's not making any false claims -- or at least no more false then VW claiming the top speed of the GTI is 130 mph, even though you can't legally drive that fast on any road.
For another, AT&T isn't late with MMS support -- yet. This means that even if they never deliver it, this claim would need to be rejected because at the time of the filing no contracts have been broken.
Looks to me like some amateurs got a hold on some prepaid legal docs and filled them out poorly...and will wind up paying for wasting a court's time.
Look -- all of the cell phone companies in the US are god damn terrible compared to those in more densely populated areas. And they're all amazing compared to those in more sparsely populated areas -- ask a Canadian what kind of service they get for $70 a month. I've had Sprint, AT&T, Verizon and T-mobile and of those, AT&T has so far offered the best service for the price in my local area -- all the more impressive considering how far behind their network was, and the millions of new bandwidth hungry users they had to support along with the iPhone.
