I picked up the 8830 and I love it. I'm coming from a Treo and have never used a BB before. Everything about this device is awesome except for the fact that Verizon locked the GPS. I'm considering switching (I have 30 days to do so) to Cingular or T-Mobile?

Is the GPS unlocked on the 8800 with both Cingular and T-mobile? Will I be able to use google maps/bb maps with both?

Also, I can't seem to figure out Cingular's pricing for data plans. I want the $39.99 minutes plan with unlimited data. What's the total cost going to be?

Thanks!!!
