Had the unlimited AT&T from day one of first iPad bought an AT&T 4g. New iPad I saw no difference in the speed from 3G to 4g. Brought it back for a Verizion now when I do a speed test the needle is buried off the chart speed with Verizion so glade I returned but it would have been nice to see that kind of speed with my unlimited AT&T plan had that from day 1 I'll miss it
