Well the problem seemed to start while I was downloading apps so I deleted all the apps I had downloaded other than the facebook one because it won't let me.
have you tried a factory reset
hold camera,vol up, power till you get the yellow recovery screen,
use vol down to get to Factory Reset/Wipe Data (been awhile since i used stock)
press camera
vol down till you get to yes press camera
when done press camera on reboot,
you will have to put in your gmail stuff again and let it sync but this will put it back to factory condition and allow you to start over.
Facebook app is preinstalled, you can't delete it without ROOT on the phone,
