The much awaited iPad 3G is finally in the hands of iFixit!

The Wi-Fi + 3G iPad. We got a sneak peak of the internals of this tablet a month ago by poking around on the FCC's database.

The 3G iPad is visually distinguished from its Wi-Fi-only sibling by a black plastic RF window.

The 3G iPad supports UMTS/HSDPA on 850, 1900, and 2100 MHz and GSM/EDGE on 850, 900, 1800, and 1900 MHz.

In a dramatic shift for Apple, the iPad is unlocked, and not tied down to a specific carrier.

Alas, in the US, AT&T is the only carrier that operates 3G on frequencies the iPad supports. T-Mobile should work, but only on the slower EDGE network.
