I recently bought an N800 that promptly died after one day's use. I've read all the threads here about this weird "won't turn on" phenomenon, and tried everything I could (bought a new battery, looked for the magic spot on the power button, etc.) with no success.

I have made arrangements with the seller for an exchange, and here's my dilemma: During the brief time the thing worked, I saved some bookmarks and log in info, and now I can't figure out how to erase all this since I can't turn the device on. I can't get it to turn on long enough to update the software, which would (I think) accomplish what I'm trying to do. Am I just SOL? My plan is to change all my web site passwords if that's what it takes, but if there's another way, I'd sure like to hear about it.
