Hey guys just wondering what would be best for me to do first I just posted my 1st gen iPhone on craigslist and people want to buy it. If I sell it then I'll be without a phone. once I sell it do I have to cancel my iPhone service with ATT and then wait until I get 3G and then do the activation like before? Or do I like keep my plan and call ATT and tell them to upgrade to 3G plan and put current plan on hold. Should I get the 3G then sell off my current phone or sell current first? Any help appreciated.
