OK, I'm breaking down and asking for advise. I have had a Palm Centro (no tomatoes, please) for about a year and a half. I've been a Palm user for over 10 years, but am ready to make to move to the iPhone. I am already on A&T, but don't have my full upgrade until October. Do I try to negotiate with AT&T for a 3G now, go ahead and pay the full upgrade price, or wait until October and get the new one?
