Which Nokia Symbian Phone and what SW to use

[JGaard]

Hi.

I'm looking for a new Nokia Phone.
So I want to get one with GPS and WLAN.
Which one should I get and what SW could be used for wardriving.

Also a bit off topic SW for locating the phone by sending an SMS (text message to it) and SW for GeoCaching/GeoDashing has my interest.

Kind regards J;-)
