Well I picked up the PN820 the first day it was out and currently I love it. I have been drooling for a flip phone with WinMo for YEARS. The last of it's kind on the big V wa the sCH-i600 which was a beast, and the 640 never appeared. It certainly won't win any beauty contests, but as far as functional, it wins hands down.
Overall I can't complain about much except for the external antennae. Considering this phone has been poking it's head up for a release LAST year, it's not surprising.
I just purchased the belt clip and extended battery yesterday, as I was finding my battery life dying during the day. Not because of poor lifeo f the phone, but because there is so much I can do with my phone now, that I find myself using it more and more. The ext battery adds alot of weight to the phone, but not THAT much more thickness to be annoying.
I just wish it had GPS or Wifi (Though I do have a data plan).
If only VZW would allow Blackberry connect on this phone I'd be thrilled as well, as I hate my BB8700C for work mail. The Windows Live client allows you to get Push mail from your live mail account for free (Data charges from carrier apply), and to always be on Live messenger. The Voice clip feature is awesome while driving
I did contact UTstarcom about a possible OS upgrade to WinMo 6. They said one had not been planned, but that an update will be posted for the PN820 in May. They did not say what the update addressed.
You can find a ton of information on the PN80 wiki at http://www.pn820wiki.com
and a discussion on HowardForums seems the best so far: http://www.howardforums.com/showthr...d.php?t=1023203
