iCapture

Here's another accidentally discovered iPhone feature that I never knew existed. For some reason, I was looking through my camera roll on the iPhone (I almost never use my camera phone) and I discovered a bunch of screen captures, and I had no idea how they got there.

So I did some digging, and learned that if you hold down the Home button, then press the Power/Sleep button, the iPhone takes a screen capture and adds it to the camera roll, where it can then be transferred to a proper computer.

Note that this only works in the iPhone 2.0 software.
Pretty cool. I don't know that I will ever need this, but it's good to know that it exists.
