Hello, Here's my dilemma. I currently am on a 2 year contract with AT&T. Start date: 9/12/2014 End date: 9/12/2016 I plan on switching to T Mobile. IF I pre order tonight on T Mobiles website 9/9/2016, will it trigger the ETF and start the whole transition process with T mobile? Or will all that occur when I get the phone on 9/16/16, which by then my AT&T contract would have ended. Thanks for any help!
