I'm sure you can easily switch your phone out with your friend's. My stepbrother switched his phones all the time under Alltel, so I don't know why Verizon wouldn't be the same way. My advice is to go into Verizon and talk to them. I switched from Alltel to Verizon, like you, and they were really good about letting me get a new phone when it was time and stuff. I have the EnV Touch, and I was having problems with my first phone and they were really great about getting me a new one and stuff. Good luck!
