Hi.
When I read your post two days ago. I felt this impulse that maked me wake up today and came here to answer you (or maybe was just a false standby call...)

You have answered yourself on you own message...
"It seems, the things I wanted this device to do, are all possible, and I've learned how to make them occur, but I have to make it happen."

And this is where all the fun is. If you wanted just a phone you wouldn't buy n900. Android phones (from the same time and even newer) are really far, far away from n900 (ok, their gui is somehow nicer). But you surely don't have the hacking possibilities that you have in n900.

comparing...
You have a real computer in your hand, android's owners have a kind of a dumb terminal (your a unix guy, you know what I'm talking about).
I always had this smartphone/gadjet paranoia, a few years ago I had a Windows mobile htc tytn, it was a great phone, HiFi,3g,cam,keyboard... I thanked god that it was a free, I was really fed up with it after 2 weeks. I will NEVER buy another windows mobile device (unless I can boot linux under it).

So, getting back to the point. Don't blame on one function that doesn't (still) work as it should. You knew that this would happen when you bought the phone. And confess that you like the challenge of making-it work. If you didn't owned it your life wouldn't be that fun.

regards
Tiago

ps:if you still wan't to sell-it cheap, I give-you 10 bucks and relieve you from all that weight
