I bought an already activated iPhone off craigslist, the guy activated it and signed up for a 2 year contract, but then didn't want it, and then he sold it to me, but he took out his sim. So all the features on it work usin wi-fi, except the phone feature. Can i, using the hack to use my existing cingular SIM (no 2 yr contract) but then can I call AT&T and get a data plan for a "regular" phone ($20), and can I safely use that on my iPhone with unlimited use and not signing up for 2 year contract? let me know what you guys think.
Also, will this work?
