Ok, I seem to be a little stuck here. I had a 2GB AT&T Data Plan on my iPad1 (and still have it) but yesterday, took the plunge and scored a good deal on an iPad2 so I went ahead and bought it (also AT&T 3G) but I can't seem to figure out how to get my data plan loaded on that device. When I goto the Data Plan settings, it wants me to sign up for a whole new plan all together but doesn't give me the option to login to my AT&T account and activate it. Is there a certain way to do this or do I HAVE to sign up for another account. I'd like to use my other account being that they just charged me $25 for my monthly plan two days ago! Thanks in advance!
