HTC Desire Delivered - First steps help on charging

[Lostprophet]

What would you folks recommend on charging the Desire? Straight away charge it or use it until battery is flat then charge it?

Cheers Mr Will.

Do I need to charge it for a certain period on the first charge? Like 12 hours? sometimes people recommend charging it even if it is fully charged in an hour!
