Apple is recalling some Verizon iPad 2 units. Don't worry too much, they say it's a small number. It turns out that there were a few iPads that went out but happened to have the same UID.
According to reports, this could cause problems if Verizon's internal system were to try to identify the affected units, it would identify them as the exact same iPad. This could cause major issues if several of these were to connect on the network at the same time.
Based on what we've read, the only way to resolve the issue is to return the tablet. You will have to get a new iPad, which is easy if you live near a retailer. However, it can be a real pain if you have to ship it.
