cannot get back automatically to runlevel 5

[k31s3r]

Hello,
running 64-bit Fedora 10 with original installation runlevel being 5.

So, there was this need for working with runlevel 3 for some days, then I've edited "/etc/inittab", changing line

id:5:initdefault:

for line

id:3:initdefault:

and the system went well, restarting automatically on runlevel 3.

Now it needs to restore its original runlevel, that is 5.

I've edited "/etc/inittab" to its original state but the system keeps starting on runlevel 3.

Also, I've tried

# init 5

and

# telinit 5

both commands load X and the login screen but then when it restarts, it gets back to runlevel 3.

What can be done to get this system back to runlevel 5, automatically, during its INIT process?
