I've had the phone for almost 12 hours now, and some unexpected reboots as well.

And another as I was typing this (luckily on my PC). Perhaps it's because the battery is full and charger still connected. I'd just opened up a page to get a podcast and had gtalk open with a friend.

I have only installed from Maemo Select/Extras repository (no devel or testing at all).

PS. I'm doing the same as I did when I got my Bold and N82, no SIM card for a few days, just wi-fi to test it out and play around.

PPS. It's only started since I switched on bluetooth, to transfer files between my N82 and the N900.
