I'm currently running an 8GB Jailbroken iPhone with Firmware 1.1.2 and my bootloader version is "4.6_M3S2".

What I would like to do is update to 1.1.4 and then unlock my phone. I'm wondering, whats the easiest way to go about doing that? Should I restore first, or is there a program I can use?

I am jailbroken via the Apptapp meathod so I'm new to all these programs and GUIs. Any help would be great!
