I don't believe in disabling the Watchdog function, and I have never even tried to do so. I don't understand why you all are having such problems; I have been indiscriminately installing every beta whatever I can get my hands on, with no serious problems since I did the firmware upgrade.

I have refrained from going into red dot mode, or whatever you call it, or doing any other obviously risky things. I use my N800 many hours every day and have since January.
