So I decided to try out an AT&T LTE iPad so I can test the speeds and coverage for myself. However, it seems I need to use the SIM that came with the new iPad. Putting the SIM from the iPad 2 results in a message saying the device requires an AT&T LTE SIM. A search of the forum brings up the new feature of easily transferring the data plan to the new iPad by logging in with your current AT&T iPad account. Great! But now this has me wondering. If I don't keep the new AT&T iPad, can I transfer the account back to the iPad 2 using the same method? Or can I change the IMEI and ICCID from the att.com/ipadlanding site to reflect the iPad 2 settings? I don't want to mess this up. Thanks.
