I decided to get my 4S jail-broken. After jail-breaking from the evasi0n, everything went smoothly (as far as I could tell) Problem occurred after the entire program was downloaded and it rebooted my 4S. Now it is stuck on the reboot page with the white apple symbol and it refuses to start up. I have force reset (holding power and home) and reboot, and it still remains stuck in the reboot phase. At random times it powers down and restarts back to the reboot screen with no improvement. I have tried to restore from recovery but that doesn't work. Any ideas???
