Since a few months I have a black HTC P3600running Windows Mobile 5.0. Today the distributor in Sweden released a new firmware which enabled the GPS receiver in the phone. How great!
The phone has WiFi, Bluetooth, UMTS, GPRS, GSM, and now also GPS :-)
Nice feature: you can switch to a profile which stores the GPS location in the EXIF data if you take a picture.
Google Maps for Mobile works perfectly too with GPS tracking. Wonderful!
(does it show I'm impressed? ;-))
