I bought my Desire S in one city (Brisbane, Queensland) while on holiday. Having returned to my home city (Canberra, ACT) I find the default time zone for new calendar entries is always Brisbane. Similarly, when I tap on the clock on the home window, the list of cities shows up with Brisbane listed as my current city. I have managed to list Canberra as my home city, but it still thinks I'm in Brisbane. I've tried all the obvious things (that I can think of) - e.g. manually setting my location, automatic setting using GPS etc. Despite all this it still shows Brisbane as my current location and defaults to Brisbane time zone in new calendar entries. (For non-Aussies, Brisbane is the same time zone as Sydney and Canberra in winter but doesn't go on to daylight saving in summer.) Any clues from anyone?? I suppose I could solve the problem by moving to Brisbane but I was hoping there was a simpler phone-based solution.
