Just finished my testing with swaping a sim card from another carrier, and I can tell you it works. I put a sim card of my friend's phone,from a carrier here in Puerto Rico that's called "Claro" and set the tp2 for gsm only and inmediatly the edge sign appears and when I make calls it was working as it was my friend's phone, his phone # appeared not mine(my sprint own)my tp2 work just fine, receive and make calls normally, now i'll be looking forward testing with at&t here in Puerto Rico. I;ll let you know.
