How Do I Safely Restore a Jailbroken 1.1.4 Iphone?

[GLClayton]

Hi,
I know this may sound dumb but i have not been able to find, on the forums, if i can safely restore my jailbroken 1.1.4 iphone. the reason i ask is because i have read about some of the iphones being bricked after they were restored and updated, which is what i want to do to get it from the 1.1.4 to the 1.1.5 update. please help, i run on mac and i am not very good with these things.

this is what i have done since i used to have a version1 iPhone and unlocked it. You need the iLiberty + tool. What i did was when i needed to restore i would click restore the normal way and then it would relock the phone, then i used iLiberty+ the only purpose was to use its activation method which activates the iPhone. Since the iPhone now is activated you can use Pwnage 2.0 to install firmware 2.0.0 on there!

Stick it into DFU mode and let iTunes work its magic.
