I reflashed yesterday after memory problems and reboots and I was hanging out at the 34th street mall, trying to get a signal and my N800 kept rebooting, rebooting, and rebooting.

It was very upsetting. I have 2 -2GB memory cards.

I am going to exchange mine at the Nokia store later today. It could be a fluke.

Regrettably, when deliveries are made, the Nokia store probably got nothing but the Korean made one...
