Finally got down to reading the User Guide (I bought my first iPhone on Friday) and I noticed that in the manual it says do not charge the iPhone through the USB Keyboard (I have an iMac from Oct. 2007). I've charged it twice through there with no problem. In fact, my phone battery was low last night so I plugged it in, left it in over night and came back in the morning and it was fully charged. The manual says that if you charge it to a computer that is asleep or standby (which mine was- i always hit the button on the back at night) that the battery will drain - but it didn't. What the heck is going on here?! Thanks for any help.
