i flashed mine, just ensure you follow the instructions, as the nokia flashing software isnt suppose to be used by the general public. It should require a dongle but there is a way around it (its all explained) and you also need to run an update and install various apps to do it.
As for the phone...its mint!! camera is really good, and the WiFi is great! pages load at braodband speed, and look exactly as they do in a normal browser. Iv tried all my websites in it and other than flash components they all look spot on.
There is also the ability to browse your pc for music/pics/videos etc and either show/play them on your pc via remote control from the phone, or copy them over to the phone to play on there!
it has hung a couple of times on web browsing but generally iv not had any problems with it! just need to buy a 2gig SD card now
