Ok, well I thought I'd try and get a thread going that would be mostly aimed at people who have just got their hands on a Desire. It seems to be the same story over and over: we get our new phones and spend a week or two (or three) trying to get our heads around it. I personally spent (at least) a week fart-arsing around with Advanced Task Killer and we can all agree what a complete waste of time (and battery) that rancid little application is. So, my number one tip for new users would be: DO NOT INSTALL ADVANCED TASK KILLER!!! What about you guys?
