Hi guys! Newbie here!

I have an iPhone4 with a baseband of 01.59.00, version 4.0.1 and is already unlock. Is there a way i can upgrade it to iOS5?

It is from US and it used to be under AT&T .. Thanks for your help in advance!

I really need a help guys! Im not familiar to basebands, jailbreaking and other stuff. All I want is to have an iOS5 working on my iphone4
 
To stay unlocked you will need to keep your current baseband.

You need to wait for the JB.
