In Need of an iPhone 4 Nerd

So right now im using an iphone 4 4.3.3 4.10.01 phone that is locked to ATT and I am using it in Canada using a GEVEY SIM unlock. I want to update my phone to the new IOS5 but I read that in order to keep my GEVEY sim working i need to preserve my baseband. I have literally no idea how to do this.
