Hello, new poster here and I had a quick question about selling the iPhone 4 that i've already activated. I've received the phone today and I'm dissapointed with it's reception. I spend A LOT of time on my phone, and my 3G seriously gets better reception than the iPhone. I'm thinking about riding the hype wave and throwing it on eBay for 1 day auction. Problem is.. I've already activated it, and I obviously can't put the MicroSIM in to my 3G. Should I call AT&T and ask them to activate my old SIM card or get a microSIM> SIM card adapter? Any help is appreciated.
