I think at this point we can only confirm this for 4G only. I'm not certain the 3G is carrier specific. AS evidenced by the fact that you can use world 3G, and the way you can take an AT&T iPad 2 and just put a foriegn sim in it.
Why can't I take a Verizon iPad 3 and put an AT&T SIM in it?
----------
My question isn't related to LTE, I want to know if I can use AT&T's *3G* network with the Verizon LTE model.
I'm leaning towards a no on this one, mainly because this is the first CDMA-capable iPad that can be used on a competing network, they will probably do the same thing they did with the iPhone 4S, and lock the ability to use the new iPad with AT&T (but hopefully not, T-Mobile, as AT&T iPad units can connect to T-Mobile, and that would make a pretty bad impression on Verizon iPads as well)
For me, I've finally decided to get the AT&T one, as someone here pointed out, if LTE is not available, the network options that the iPad can fallback to is all the way back to EVDO on Verizon, while AT&T offers "4G" HSPA+ 21Mbps, which is the same one used on some phones like the HTC Inspire 4G which should pull up speeds of around 3-7Mbps, way more than good enough for me.

I believe the AT&T version doesn't have CDMA capabilities to be on the Verizon network (when 4G is not available). I don't think it's a technical limitation as it is a financial one. The extra $130 is the "subsidy" of which a portion is paid to the specific carrier in exchange for the no-contract data plans.
It kind of conflicts because technically, it doesn't cost Apple any less to get a GSM-only radio chip than a GSM-CDMA capable one (for example, Verizon iPhone 4, could've been marketed as a global phone if they added a SIM card slot).
I'm leaning towards a maybe, it can be a no because the seperation of the new iPad could also mean different 3G radio chips, but towards a yes, because they could both feature the same 3G radio chip with different LTE radio chips for both models.
And my two cents here, is that it would probably cost Apple less to use the same 3G radio chip across all new iPads than to source two different ones since buying wholesale from only one manufacturer will probably save them more money.
Either way though it doesn't really matter, I mean unless you're planning to flash that thing to metroPCS or something (if you even find a way) why bother?

Bit the bullet and pre-ordered the Black 64GB AT&T iPad. I originally included the free engraving but cancelled my order and reordered it without the personalization in case I give it back.
As an iPad 1 AT&T unlimited user and considering the fact that I had positive AT&T iPad experience here in the New York City Metro area and the fact that two AT&T representatives (local store and AT&T national) said I can move my plan over made the choice a no-brainer. Another factor was that in the New York City Metro area the 4G coverage maps implies a much broader AT&T coverage area than Verizons. As an example, the Verizon map shows half of Long Island (Suffolk County) as being 3G only. The AT&T map is completely covered in blue (4G) for miles and miles around the New York City metropolitan area.
I figure that if AT&T pulls a fast one and doesn't allow or highly cripples the unlimited plan I can always return the iPad (within some window) and switch to Verizon - hence the backing off of the personalization - which I assume would complicate the return process.
truth be told though, even if they do pull a fast one and cripples the unlimited data plan, AT&T is still faster in overall terms than Verizon, since LTE is not so widespread yet, the networks you fallback to will be faster on AT&T than Verizon

I saw and read that.
Doesn't seem like the same thing.
I may be wrong, of course. I don't know much about it.
I've never had an AT&T iPhone or iPad.
Will the 'iPad 1 AT&T Unlimited Data sim' on ebay work for me with a new AT&T iPad 3?
*For 4G.
It probably will, there's no reason for it not to, since people grandfathered into the unlmited data plan can also use it on other LTE devices on AT&T (Samsung Galaxy S II Skyrocket and such). 90% chance it will, and if it doesn't you can always just get the $50 plan.
