Hi all, Been looking to buy an iPad 2, and have decided to go with the 64gb size, but on the fence for whether to do 3g or wifi. I will use it for work (and have wifi at home and work), but will be on the road some times without wifi and have thought about tethering when needed. However, I recently came across someone who was selling their iPad 2, 64 3g with att. However, they are selling the iPad with their att unlimited data account to go with it for about $800. I was informed that the current owner had dropped and shattered the screen, and it was replaced by Apple recently. The serial number he gave showed that Applecare is good until March 20, 2012 and is eligible for extended coverage. Of course, if I meet up to look at it, I will verify the serial number is the same and the condition of the iPad. My question is whether this would be a worthwhile purchase, and if there is a way to verify that they actually have the unlimited data plan. If this one doesn't work out, I will most likely buy a new one - still deciding between wifi and 3g. Any thoughts would be appreciated!
