The other day I attempted to register my cellular Data Account with y 32G/3G iPad and everything seemed fine until it attempted to verify the activity (or whatever they called that step) and then all of a sudden the signal strength indicators and "AT&T" (in the upper left-hand corner) disappeared and was replaced by "No Service" (and my daughter's iPad showed 5 bars). Ever since that time the upper left-hand corner icon has looked the same ("No Service"). What did I do wrong (if anything)? I do recall a question as I was signing up, it asked me if the "service area" was the same as the credit card address (which made no sense at all if I was going to be at home, so I answered "No" - because I wanted to use it on the road). Does this have anything to do with the price of tea in China?
