I canceled my iPad 3G 250mb data plan, thinking I could reset my iPad and sign up for an unlimited data plan since I could when it was new; at least canceling and doing a reset of the network settings from the settings menu on the iPad did nothing but cost me to loose the 250mb data plan I already paid for. How do I 'un-cancel' the data plan and get what I paid for back? Right now instead of "view account", it brings up the original sign up page asking for my information, name, etc. Or if fully reformatting the iPad will get me back to having the option for unlimited, I'll do that. I just hadn't backed up my data when I tried this.
