Yeah, don't you remember Diablo, AT&T withdrew that unlimited plan one month after the launch of the first iPad. And it is truly unlimited too, AT&T doesn't throttle iPad subscribers. But I have pretty decent WiFi here in the city anyway, so I needn't abuse it. Unfortunately at my farm upstate there is no decent DSL and AT&T's 4G there isn't LTE. But at least it is much faster than the old 3G: about 5 Mbps as opposed to around 1. And the sales guy at the AT&T store where I purchased my new iPad told me that they were busy installing 4G equipment so it shouldn't be a long wait. Glad I bought it there too because it was quite a process, transferring my unlimited account, don't think they had ever done that before there (a small hick town). Anyway the Apple Store doesn't handle that kind of thing, the employees at the NYC stores could only answer my inquiries with "Good question!"
So far my new iPad is performing flawlessly and getting great battery life now that I know to keep it charging for at least an hour past reaching 100%. Love the screen, and the fact that it can be dimmed down so much further than on the first two generations. Sound is superb too, am right chuffed over all. Best Electronic Device Ever.
