I picked up my N900 on Thursday and it was quite nice, but it kept cycling thru to the Nokia screen if I was doing something. It wasn't constant but happened a few times during each maybe 15-20 min session of playing with it. Well then last night I finally got time to add contacts and emails, and setup FB and other things and then I hooked the unit up to my Windows Vista computer and it kept going thru the DOTS loading mode on the screen (the screen that comes up after Nokia logo) well 30mins later it still was going and the thing would not show up on the pc and would not shut off. SO i took the battery out, then put it back in after I disconnected it from PC. Well then it got stuck on a DOT on the loading screen and never loaded up after that, many battery in and outs later i Gacve up and left it on the charger all night. Well woke up this morning and it was a brick, it would not even turn on, light up, do anything at all. I called tech support and the guy told me I was the first call they got about N900 problems, he said congradulations out of under maybe a possible 2000 people that had the phone I won the first brick. LOL. Well I called the NYC store and told them the tech said to get a replacement thhru them, but they were out and said it would be days before one arrives so they took my name and number. Luckily a few hours later a female called back from the store and said someone canceled their order and I could come get that one . SO I got a new one again, and I hope I have no problems. When it was working, I was so happy with the unit, it was a shame I got to be #1 owner with a dead one.
