I just have a quick question about my AT&T service on my iPad. I pre-ordered my iPad the day the option became available, and received it the day it came out. That day I activated my unlimited data plan. Since then, every month I have been paying the $30/mo. Each month, I have gone over 2gb. Next month, I will use very little, or no data on my iPad. My question is, if I cancel my unlimited plan for a month, will I be able to get back in? What if I buy the $15/mo. plan for a month? The unlimited option does not appear in the settings, and I've heard that you have to call AT&T. I don't want to sit on the phone for several hours just to ask AT&T if I can do this, so if anyone here has done this, I would really appreciate any information. Thank you.
