T-Mobile UNcarrier 4.0Lots of people are excited for T-Mobile’s upcoming UNcarrier 4.0 announcement, but we have precious few hints on what it could actually entail. (We basically only have one tweet so far.)

While I’ve already made public my wishlist for what I’d like to see the nation’s fourth largest carrier do next, some people are speculating that T-Mobile might offer to cover the early termination fees from Verizon and AT&T for new customers. According to an anonymous tipster to TMoNews:

…he’s teasing a project code named “houdini” which will give switchers up to $350 in credit when they switch to TMO… Emphasis will be on families switching up to 5 lines regardless of contract end dates…

New customers will receive instant credit when they trade in a smartphone, then get a credit for the ETF charged by their old carrier when they submit the final bill to TMO.

Interestingly, Sprint’s ETF fees are not mentioned in the rumors I’ve read, which lend even more credence to those potential merger rumors.

In any case, T-Mobile will officially announce the next phase of its UNcarrier initiative at CES on January 8, and we’ll be there to report on what is unveiled. At least we don’t have to wait long for clarification!
