I am doing all the research before I jump in to get an iphone. Lets see within weeks of buying an iphone 3g from AT&T with $30 data plan and a new 2 yrs contract..... My iphone gets lost/stolen...and I can't find it. If this happens, my only choice would be to use my stupid old phone when a new SIM CARD that AT&T will give me. What will happen to my $30 data plan? will they take it off since old phone does not use any data? Will AT&T charge me extra for anything else? I do not plan to get out of contract or anything...I have been with AT&T for so long now.
