(adsbygoogle = window.adsbygoogle || []).push({}); Ok I have been away from the Iphone jailbreak scene for a couple of months.
I'm currently on 4.0.1 with 05.13.04
Somehow Cydia grabbed my 4.1 SHSH files without me updating.

Now i'm thinking about going up to 4.2 but I want to keep the baseband as low as possible to keep the unlock.
is it possible to create a custom firmware at this moment in time? or has it not come out yet?

I think that is it ......
simply put can i update 3gs new bootrom without losing unlock?
