The rumors were true and AT&T was right to come up with a pre-emptive strike, although it might not matter much. T-Mobile's Uncarrier 4.0 initiative was leaked online and AT&T has good reason to be worried. It is indeed a plan to draw customers away from other carriers by paying their early termination fees, if they switch to T-Mo and trade-in their existing devices.
There is a catch though, T-Mobile will supposedly pay up to $350 per line when customers bring over at least three lines. This seems like a great way to draw in whole families in one fell swoop. More than likely the official reveal will happen tomorrow at T-Mobile's press event, which kicks off at 12:30PM Pacific Time. We will keep you posted if there are any other details to reveal at that time.
