I'm thinking about getting the Droid X, but my current ATT billing cycle ends June 30th. That means if I go a day or two over, they will charge me an entire billing cycle. I definitely would want to avoid giving them free money, if I was to leave them at the middle of July for the droid x. They do not pro-rate you. So if I go the Droid X route, I'm cancelling on June 30th. - What can I use for 2 weeks until the droid x releases? Any prepaid phone ideas? - Will I lose my old phone number since I'm not porting it to a new carrier yet?
