GPS,WiFi,& More

I am debating between 2 phones:

BlackBerry 8310
BlackBerry 8520

There are only slight differences between the two. Click the links above to be taken to the pages to get see more info. I am going through Cincinnati Bell Wireless. The problem I am having is with the GPS. I want to have some sort of GPS system on the phone but I don't want to pay the $10/month fee for telenav.

The Question:
If I get the phone with GPS but don't pay for telenav, can I still get some type of GPS system on the phone for free. I've heard of google maps, mapquest navigator, Bbmaps, infospace, amAze GPS, TrekBuddy, and nav4all but I don't know if that really offers any good navigation features (plus I don't know which of the 2 phones I can and cannot use the programs on).

What do you guys recommend? I mean, if I get the 8520 can I still get some kind of GPS software on there by unlocking the phone or is the 8310 the only one that comes with a GPS system in it?

Thanks so much.

Not trying to double post just not getting any replies

Google maps will work with your gps, or by using the cell towers to estimate your location. I usually leave the gps off just because I dont need the continual battery drain. I have the 8310.

does wifi cost?
