I have the mytouch 3g with t mobile. I heard that the new google phone is supposed to come out in january. And it will be unlocked to work with at&t and t mobile. I've only had my phone for 4 months and I have a 2 year contract. If I get the new google phone in a month and stop using my mytouch 3g will I be charged a fee for ending the use of my phone?
