What are the possibilities for my first generation iPhone when I come off contract next month? Will my iPhone basically become an iPod Touch if I decide to purchase a new iPhone and drop the contract on the first generation iPhone? I don't think that it would be very beneficial or economical for me to carry around two iPhones and pay two full data and phone plans. Do you think that AT&T will allow us to switch Sim cards between two iPhones? I would like to use my first generation iPhone to store business-related applications and my business contacts (over 2,000) from Outlook on my corporate Windows PC, while my new iPhone (if I decide to purchase it) would store only personal contacts (around 200) and whatever else I want to put on it from my Mac at home. I also have a MobileMe account, so if anyone knows how I can use just one iPhone to store both PC Outlook and Mac Address Book contacts without mixing the two in the same database, please let me know about it. After watching how much faster my wife's 3G iPhone is compared to mine, I am getting more and more anxious to get a 3G iPhone. All of the other stuff that gets released with the new iPhone coming out will be a nice bonus. I know that I could call AT&T and get a few of these questions answered, but I just wanted to know what my fellow Mac users were thinking about doing with their first generation iPhones. I really don't want to sell it. It was purchased on iDay, June 29, and I think it is as revolutionary as the Apple II or iPod. Definitely a keeper for my Mac collection from the last 20 years.
