spec me a phone for less than £150

[englishpremier]

I have now moved from 3 to O2. Three will not unlock my Nokia N80 that i've been using for over a year as they cannot find it registered with them (despite 3 branding all over it).

At the moment i'm using a 6 year old sony erricsion and it hardly has any singal anywhere.

I can spend upto £150 and am happy to buy a second handset. What can I get the money?

A key issue is that I use my phone as a gps (with bluetooth dongle) so need something that can run either tomtom or garmin.

Thanks

Well the N80 has a great sceen resolution compared to say the N95 etc.. 352 x 416 which is one of the highest i've seen.

i use my phone for MP3s, Sat Nav and the odd image when posting on ebay.
