Advent Vega's Cousin gets GPS and 3G
Point of View Mobii Tegra2 gets updated with 3G and GPS.
(havnt posted enough to add links to my post yet, hope this is OK anyway)
and its just a some €50 more expensive than the one without.
I have the model without these functions but i use ModaCo's firmware for advent vega.
Thing is that i have a slot for my SIMcard on the actual tablet, but it never got a simcard working on it, but it doesnt seem to be connected to anything, sadly.
