Re: 4g scam
"Personally I think that Apple's use of the 4G moniker is likely to backfire. Apple are aware that the 4G unit will ONLY work on Verizon in the USA and a few networks in Canada (even then, I believe that you have to use one of their SIMs, ie not via roaming)."
It'll work with AT&T's flavour of LTE too. In fact, the US is (unusually) ahead of much of the rest of the world with LTE rollout. You cannot blame Apple for that. LTE has been such a cock-up, it's unlikely to ever be much cop for roaming until someone designs a fully tuneable LTE + GSM + 2G transceiver chip suitable for mobile devices. I don't expect anything like that appearing before the iPad 4, and even that is pushing it.
Nevertheless, the new iPad does have built-in LTE support where available. Apple aren't responsible for the EU's sluggish adoption of LTE, nor for the fact that 4G is currently only available in North America and parts of the Middle East. (I've heard reliable reports that Dubai has adopted the same LTE frequencies as the US carriers, so yes, the new iPad's LTE features do work there as well.)
LTE is generally accepted as a "4G" technology worldwide. (Note that there is no standard for what "4G" actually means. It used to refer to systems capable of higher speeds than current LTE installations, but this requirement has long since been dropped.)
