Considering turning in the VZW Tab for the T-Mobile Tab. HSPA+, 16gb of internal storage, no overage fees for 5gb cap, 39.99 for 5gb. I apparently live in one of the "4g" areas now, but I don't know how the "No Roaming" thing will work for me. I don't want to be driving down the road using Google Nav and have the signal drop out because of Cell coverage. Anyone mind helping me choose? Will there be a restocking fee for VZW? I live in the Richmond, Va area.
