So I've has an iPad 2 since launch and suddenly yesterday my iPad's 3g verizon is not working. I fiddle with different fixes and then I say screw it and call verizon. They tell me my iPad has a twin (same MEID number or something) and it apparently happened with a few, but what verizon people are supposed to do is advise the new owner to go return their new iPad for a new one with a different number... instead this twin of mine got their iPad activated and mine was forced to deactivate. Verizon tells me they can't deactivate the other one and reactivate mine because that's against the rules, so I have to return my day 1 iPad to get a new one. Some may think, oh nice new iPad but I have to backup all my information and I have to drive to the apple store, I have to get rid of my iPad that has a 30 dollar non-removable skin on it... all because a Verizon person decided that it was ok to deactivate an existing account to open a new account. So if your verizon log-in suddenly stops working and it has that wonderful error message of cannot activate cellular data network, it may be because your iPad has a twin and someone at verizon just deactivated your account even though they aren't allowed to.
