Just a word of warning if you have one of these phones, the update does not seem to work too well, ended up with test mode stuck on the screen and had to remove the battery to get it going again.
I had a similar experience with an N82 a while back. Update screwed up main screen display, and no way back from it.
I do like well tested software - shame there doesn't seem to be any about. :(
I do have an SE T250i I can fall back on if it had needed Nokia's attention.
