there are a few different programs to capture the screen from the ppc. I used to use screen capture directly on the device. It saved to the phone but then I had to transfer to the computer to post. Which was a pain in the ***.
But then I found a program called mymobiler. It runs on the desktop. When you connect your phone to the computer you can control the ppc on your desktop and take screen shots. I started using this when I needed to take screen shots of my s2u2 wallpapers and couldnt do it with screen capture since the device was locked.
At first mymobiler connects everytime you connect your phone its kinda annoying but you can stop that in the settings. Check it out. Its nice and most importantly is FREE. Just the way I like it. Get it at
