Ok, I'll try not to be wordy but LISTEN UP!!!! I pre-ordered and got my iPad 3g on April 30, signed up for unlimited plan instantly, I haven't had a problem until now. I got an email saying that my payment didn't go through for my auto-renewal unlimited plan, which hit me with a cause there was not prob with my card. I called AT&T to clear it up and find out what the prob is, as I still had 22 hours left on the plan to correct it. The AT&T rep did not know what happened with my account but that I only have the options now of either 2GB or 250MB. That obviously didn't go over too well and we squared things up for now, but the following is very, VERY IMPORTANT. Current 3G Unlimited Plan customers that are setup for auto-renewal on their credit card, AT&T will charge the card 24 hours before the TIME/DAY that your plan expires (Example: If you signed up for plan at 6:30pm on May 31st, then at 6:30pm on June 30 your card will be charged). Remember that it's a 30 DAY plan and not a monthly, so every month it'll be a different day (due to days in month, right). ANYWAY, if that charge does not go through for any reason, AT&T sees that as a breach in contract and you have officially forfeited your right to the unlimited data plan and can not get it back. So I asked the obvious question, can you change the card information or is the card assigned to the auto-renewal and the 30 day auto-renewal your only ticket to glory.....and he said confidently, YES. I am not referencing a site, official statement or anything other that the customer service guy at AT&T who gave me all of this information. But he did say that they were running into a few of these lately. YOU BETTER MAKE SURE THERE'S MONEY ON THAT CARD, MONEY IN THAT BANK AND DON'T CHANGE A THING WITH YOUR CELLULAR DATA ACCOUNT ON YOUR IPAD!!!!!! AT&T will give you a shaft that even Richard Roundtree would be envious of. Pardon my EXCESSIVE USE OF CAPS AND BOLD, but after spending an hour on the phone with them and finding this out........my peeps should know and be very concerned. Peace out and stay unlimited Oh yeah and to top it off, AT&T is training their reps to blame Apple for not anticipated the data usage due to the number of devices. HAHAHAHA, oh my that's funny. But that's neither here nor there right now, I am very upset.
