Should some buyers in the US be concerned which iPad they buy?
Assuming you don't prefer AT&T over Verizon while in the US, but instead want to be sure the device will have the correct antennas, not need messing with APN settings, configuration profiles and/or jailbreak the device when the time comes to use it outside the US of A.
Are there any internal antenna, firmware, or chipset differences to allow the Verizon iPad to work better with the legacy Verizon (non LTE) data networks? If so, is this better or worse for world usage or specific countries or locations?
My impression from Apple's marketing is that they are identical devices made from the same parts and manufacturing process and only get differentiated when the micro sim is inserted and it gets labeled a Verizon or AT&T iPad for sale in the US. Note: although I'm focused on US iPads, if an answer is general for iPads worldwide, awesome! However, I don't need that information for the purposes of this question.
