The brief appearance of a T-Mobile banner discovered by Droid Life appears to confirm that T-Mobile will cover an entire familys Early Termination Fee (ETF) if they switch to its network. Its long been rumored that T-Mobiles eccentric CEO John Legere would use his companys CES press conference to announce a plan that will make it easy to switch from rival carriers. Given the companys ongoing spat with ATT, many assumed the offer would be limited in some way to would-be switchers with ATT lines, but the banner ad, if genuine, dispels that theory. Second, you wont be able to bring your own phone and pick up a cheap contract — youll have to choose a device directly from T-Mobiles range.
