My iphone is in firmware 1.1.1 and is activated and unlocked, I have A problem when I have to restart, because is very difficult to me to access the initial screen.

I've been told that meybe I have to correct some permissions, for instalnce lockdownd, which my octal is 0555 and someone to me to correct it to 0755. Since it doesn't seem to be the solution I wonder if you can help me with this by telling me which files by SSH should I check that may affect the restarting.

Thanks in advance.
