which OS are you using and what version of FB? i mean the more info you give us, the better we can help you. unless you are just ranting aimlessly and not looking for help then disregard.
Have you done the typical troubleshooting? Battery pull etc.
probably wont help since the device reboots itself while using the app. ive seen people complain of this before in other threads. are you using the most recent FB?
