With this little MPKG program you can make screenshots of your phone screen very easy.
First your Motorola ROKR E2 must be at least 36P firmware or higher.
Then copy Cap_E2.mpkg into your SD card and install it (just run the file trough your File Manager). When you do that you will see a new green computer icon on your desktop. Run this capture program to take a screenshot of the Motorola E2 screen (when taking a screenshot it will make a "jingling" sound).
Defalt set is to take 3 shots in interval of 1 second
The files are named with pic_n (n for number), saved in the directory "cap" on you SD card
