I wish Cyril and company the best. After 3 weeks tuning/calibrating Navizon with my GPS in the DC area, covering and recovering the same areas, the best the Navizon software could do without GPS (i.e. cell-phone tower only) was place my location within an approximately 1/2 mile area. That was the best it could do - it was often much worse than that. This kind of performance is pretty much useless for any form of GPS application, so Navizon no longer resides on my phone.

Perhaps someday it will rival Verizon's VZ Navigator in performance, but for now it just doesn't do much useful.

In order to be fair, you need to compare apples with apples. VZ Navigator works with a GPS chip when you're outdoors and with cell positioning when you're indoors.
In an indoors situation it will give you the same accuracy: cell towers cover several miles (especially the CDMA ones) so it can never be a surgical precision. Only that with VZ navigator you won't know how precise it is as it will display stuff around you and not where you are (when using cell positioning indoors).
You didn't like it, that's your absolut right. But I would simply say:
1) No one said you could get super-accurate when using cell positioning on Navizon: it's good enough however to find stuff around you when you are lost in a new city. And Verizon won't disagree here.
2) You could have gotten a 20 meters accuracy just by turning on wifi (Verizon doesn't offer wifi positioning)
3) As far as I know, VZ Navigator is not available on Windows Mobile phones. Only on Razrs.
4) You need to be a Verizon customer. Lucky for you to be one of them, but Navizon works with all carriers, worldwide.
