Putting in a sim/activating gsm?
 

Hi, I have active service with sprint.. but I was wondering how you can pop in a T-Mobile sim and how that works?

Sorry, but it will not work. Sprint and T Mobile operate on two different kinds networks. Unless you have some kind of world phone, but even then I'm doubtful.

I already know it can be done.. at least with AT&T's :confused2:

Ah, I missed you had a TP2. You need to security unlock and flash a patched radio. Sprint world phones are locked for use on the domestic GSM frequencies that ATT and T Mobile use.

Data speeds may only be Edge.

There should be information in the upgrades sub forum. Search.
