Thanks Werner, I'll have a look at that. I have the Monaco V4 app but hadn't looked for any more Heuer ones of late so thanks for the pointer.
And what does the forum think of the new iPhone, the 4S? Lots of disappointment online that it's not the iPhone 5 and isn't more different from the 4, but I think an upgraded 4 is a good idea. I like the design (especially as I can avoid dropping it, so don't worry about the glass back and front) and it means I don't have a visually out of date phone now! 4 still suits me fine, but I'll see what the 5 brings in a year's time - I prefer the design of iPad1 to iPad2 so I'm not sure whether I'll prefer 5 to 4 aesthetically if the tablets are any indication...
