Are any of these programs usable with the Alltel 8330, or am I limited to only using the Telenav software that came with my BB? I have heard that Alltel has locked down the GPS in a similar manner to Verizon, but I don't know that for sure yet.

I've used Telenav and it seems to work fairly well, but I'm not really interested in paying $10 a month for something that I only use infrequently.
