So I may have to swap service providers (not really by choice, family plan etc..) I got a screaming deal on my current nexus 5 on sprint network. But it looks like we may be switching to t-mobile. I know I will need to get another phone because it has to be GSM I believe? They have a trade in offer but need to see the condition. They are asking $400 for a gsm version. Any ways around this, sucks because my phone works just fine. Thanks in advance!
