A while ago I was determined to sell my iPhone, buy iPad 3G and get a cheap phone for making calls. That's exactly what I did, consecutively canceling iPhone data plan too. In the end, I wasn't satisfied with iPad 3G (main issue was portability). So I sold it and decided to get iPhone HD when it's released. The reason I wanna get the iPhone data plan back is that I'm afraid I won't be eligible for an early upgrade (in case there's such an option for iPhone HD). Also, I hope to be one of those whose full-upgrade eligibility gets moved to earlier dates. But I know it won't happen without iPhone data plan. So the question is: how can I have my iPhone data plan back on my account? When calling CS, they ask for iPhone IMEI number. Is there a workaround? Please, help me. Much much appreciated.
