Upgrading 1.1.4 unlocked 1st iphone to 2.2?

[sowatup]

Hi everyone,

I am new to this and just finally decided to upgrade to 2.2 firmware!

Right now I am using unlocked, 1.1.4, 1st gen iPhone on t-mobile. I want to upgrade it to the latest firmware. Can some one guide me on how to do it? Or direct me to step by step guide? Please?

I currently have epc.tmobile.com hack for data, and just want to
Make sure that it will work on 2.2? Will it? This is very important to me, and that's the reason I havent upgraded yet as I wasnt sure if that data hack would work or not.

What version of iTunes will I need? Etc?

I am using windows vista pc.

EDIT: I should mention, I unlocked 1.1.4 using ZiPhone. Should that matter?

Thank you!
