Seems like the latest 4G iPad shows problems with 4G, otherwise known as Long Term Evolution (LTE), before it is fully released. The 4G iPad can work in the United States but not anywhere else. Seems like there isn't a standard where 4G is meant to be operated, and the chips that power this 4G is fixed on certain spectrum. This does not speak well for us consumers.
In layman terms, it will mean that if you have a 4G phone, you might not be able to use it overseas just because your 4G is not compatible with the other countries' network. Seriously, I would have thought after the CDMA/ GSM problem, they would have taken this into account before they start designing 4G.
It seems that it is best to avoid any 4G phones now because you may end up with a phone that cannot work overseas. That is not worth it.
