Hello,
I currently have a 7100, but am thinking of upgrading to a curve or 8820.
I would like, but don't need, GPS capability. I have Tmobile.

What are my options for full GPS (turn by turn, voice instructions, corrections if wrong turn, etc)?

What other options do I have (no voice, etc)?

Any other Tmobile users who can guide me?
If you can specify any costs (data plan, etc), thanks!
Thanks for any help. I talked to tmobile and got more confused

TeleNav is what I use...runs $9.95 per month. Works very well for me.

If you get the 8320 (Curve) you would need to buy an exteral GPS puck, as these units are WiFi instead of GPS. Go for the 8310 or 8820 to have GPS.

The 8820 DOES have GPS. There is no 8810 that I'm aware of.

Sorry John I realized it just after I typed that I was wrong on that one.

I do agree TeleNav is a nice program, including the local search feature.

Same as any other GPS-enabled BB. Have you visited the GPS forum? There's a ton of info there. GPS isn't unique to the 8310...
