Ok so today I was on my Lg Vortex doing my regular things such as watching Youtube Videos, going on facebook, and etc. My phone slowed down so I used my cache cleaner and my task killer and then accidently went to Settings Storage. Without thinking twice I cleared the data on it. Later when I rebooted my phone cuz it was being all funky, the lock screen where i usually put my pass code was gone and it went straight to the home screen >;0
I pressed the lock button to put it on sleep and when i pressed it again the lock screen just woudln't show up at all ! After that I realize that the home button wasnt working either when i pressed it
DOES ANYBODY KNOW HOW I CAN FIX THIS WITHOUT HAVING TO REST MY PHONE OR SEND IT TO VERIZON???? I am currently running Android 2.2.1 and my phone is not rooted.

Please help! Time is of the essence!
