How is your iphone home screen set up?

Another iphone query flutherers – sorry! I’ve been fiddling around with my iphone’s home screen for the last couple of weeks and I haven’t yet managed to find the ‘ideal’ way to set up all the app icons, so I was wondering how all of you fellow iphone users do it. Do you go with those apps you use most on the front page? Or the ones with the prettiest icons? Do you colour code? Or do you really not care?
