fb2bmp is a software that converts raw screenshots made trough telnet on Motorola ROKR E2 to a regular bitmap. The usage is very simple:
1. Unpack the zip archive
2. Open command prompt by "Start > Run" and go to that folder where you extracted it
3. Type: fb2bmp image_filename
Here the image_filename will be the file or path+file of the raw image that you extracted on your SD card
