Nokia X6…. fantastic !
Had mine since December. Very pleased with it.
The gps is superb (better than my Garmin). I use it with Google maps, Ovi maps (satnav) and also Viewranger.
The first two were free, the Viewranger costs but I have the whole of the UK at 1:50k in proper os mapping on the phone.
Very nice to use. I record routes, create routes, share routes to and from Tracklogs on my pc.
Other things… the camera is very good, music player is good, loads of free or cheap apps for it.
Mine came with "Comes with music" too, so unlimited free music downloads for 1 year. Added 100+ albums to my collection already 🙂
Battery life is good on this phone. ie some calls, use music player, gps for several hours, mess with phone, etc… lasts all weekend.
