I've been trying to take a screenshot using the dock application of my screen when I'm unlocking the iPod. I have a theme that I would like to post, but haven't been able to get a picture of it. I hit the screenshot icon on dock, press the sleep/power button, hit it again so I'm on the unlock screen, hear the camera noise, find the picture, and all it shows is the header with the time and then just black underneath it. Does anyone know how I can get screenshot of this using dock? Edit: After some searching on Google I guess it's not possible with Dock. Oh well. This can be locked/deleted.
