I haven't been able to find a decent GPS app for the iPhone, jailbroken or not.
Been thinking about trying out AT&T's, but for $9.99 per month... don't think I'll get around to it.
xGPS is pretty sluggish, for me... it does work, but, pretty clumsy interface.
telenav works great. i had it for my bold, and when i switched to the iphone canelled my subscription becasue it wasnt available until recently. now its back on my iphone as well! works very very well, i highly reccomend. the only bad thing about this program is that the voice sounds muffled for some reason. it did the same thing on the bold. you really need to hook it up to your cars speakers thru some connection (aux input, fm, cassette adapter) in order to truly use it well.

Unfortunately the darn car that I use, doesnt has a casette player or a aux input and I really hate my car for that one reason and only that..
