Upgrade your iphone to 1.1.3 using Itunes and ZiPhone 26 February 08

My Iphone had been on firmware 1.1.1 since I bought it and I did a complete restore when I replaced my screen. Well I found This Guide on how to update to 1.1.3.
This is very very easy and you can do it in 5 minutes not counting the download of the firmware + ZiPhone app.
Just update to 1.1.3 in Itunes then reboot and use ZiPhone to unlock jailbreak and load the proper boatloader (just tick the first 3 boxes) Click run, reboot and you have and unlocked Iphone running 1.1.3 firmware.
Here is a pick of my Iphone now with a skin and the neurox leopard theme which you can install if you have summerboard.

Good luck!
