Can the Battery be Overcharged?

I know that iPod batteries cannot be overcharged. I assume that the same is true for iPhone. Am I right or should I be careful how long I leave it plugged in?

2 17" iMac Intel Duos networked 1GB each, Airport Express, everything up-to-date, Mac OS X (10.4.9), 5 iPods in family (1st shuffle, 1st and 2nd mini, 2 1st nanos) - have Cingular!

I doubt it, since it charges automatically when its connected to your computer via USB... everyones would be overcharged if so.

It does note in the online manual that leaving the phone in the docking station can drain battery when the computer is off or sleeping.
Would it be better to leave the phone in the dock with the computer asleep, not connected to anything, or in the wall outlet charger?

Leaving the iPhone plugged into a USB adapter is probably the best bet. I'm assuming iPhones have the same technology as iPods in which there is a designated chip there to control charging and preventing the battery from being damaged if left in too long. Leaving your iPhone in a sleeping computer will drain the battery just as it would if it wasn't connected at all since there is no power going in.
