So I've heard that the best iPad 3 to get if you're going to do some overseas traveling and want to use a local SIM card for data is the Verizon version, because it still has a GSM radio, the SIM slot is unlocked, and the 3G will work with just about any international GSM band. But what about the iPad 2? Does the Verizon version of that even have a SIM slot and a GSM radio? Will it work with overseas networks with a local SIM card?
