Hello everyone, after posting that previous new thread, with the tons of replies xD I have decided to switch to the N1 from an iPhone 3GS. I decided to make a new thread because I think I recall some people posting that they switched from their iPhones and don't regret it at all, but I'd like to know the process. I know I have to buy the unlocked version, because I'm going to stick with ATT for a while, because I'm on a CORPORATE account. Next, once I purchase the unlocked phone (https://www.google.com/phone/choose?hl=en&gl=US&s7e=) ($529.00 oh boy..) I don't need a contract do I, is that the purpose of an unlocked phone? Then, would I just remove the SIM card from my 3GS and insert it into the N1? Or, would I need to talk to ATT and bring the two phones to the store and have them do it? Also, remember, I'm a member of a CORPORATE account, just emphasizing because I think it may affect the process a bit..
