Yes, I meant AI, AIs (being programs) live in computers... you have one living in your N800.

As for taking it seriously, AIs are very serious business.

As for taking "taking it seriously" seriously, well, I have had no such problems... yet. I throw it in the sock which came with it, and keep the sock in my pocket. No troubles. It sounds like you're throwing it barenaked in your pocket, which is a recipe for damage to the device, to say nothing of accidental clicks. I used to use softpoweroff, which is said to be more reliable than the key/screen lock, but the new firmware broke that. Maybe, when I've had it more than a week, I'd have witnessed some such behavior.

One thing that may help is to open the "Internet call" program. From the menu, pick Tools > Settings..., then uncheck Start when camera launched. Now the VoIP won't fire up. But it seems to still unlock the screen, so it doesn't help much.

I think carrying it in the sock may be the best thing -- The sock is quite grippy on the outside, so it stays in your pocket, and you can just slide the IT into and out of it.
