Got the new iPad on launch day and got my existing data plan transferred over with no problem. 4G (not LTE) worked fine. The next day the cellular data was dropping out. The signal strength indicator was still there but the "4G" notation disappeared. Anything I tried to do that required an Internet connection failed with a pop up that said I had no Internet connection. Resetting the iPad seemed to work a couple times but after a few minutes it dropped out again. Toggling cellular data on and off a couple times seemed to do the trick; either that or the signal came back coincidently. It did this again today in a different area. I live in an area with great 4G coverage but no LTE. After it happened a couple times I thought to turn off LTE since I wasn't using it anyway (duh) and the connection kept. Again, not sure if signal problems were going away and coming back or if something is wrong with the iPad. I've never seen anything like this with 3G on my previous iPad or on 2 iPhone 4s. Does this happen on 4G a lot? I've never had a 4G device. Or is it because LTE was on and it was trying to connect with no coverage? Or is it a faulty iPad? And if anything but the latter, shouldn't it have defaulted back to 3G (or even Edge)? At home and work I've got a consistent connection with no problems, for whatever that's worth.
