Hello everyone, I am thinking of getting an iPhone 5 at the end of the year or maybe xmas gift to myself. I have an ATT BB work phone and I have primarily been using it as a personal also. Its been over 12 years since I had my own personal cell phone. So I am thinking of getting an unlocked iP5 and trying out StraitTalk first or TMo. If I don't like those two maybe ATT. My question is if I start with ST and get a phone number, can I keep the same phone number if I decide to try TMo or ATT? I don't want to keep changing phone numbers. I also have google voice but have not really used it much. Not sure how the GV app is like on iPhone. Also, do Call Forwarding come with all service? Thanks for everyones help.
