Upgrading previously unlocked phones?

[Montyfone]

Sorry to post yet another new thread, but a lot of the others seem to be purely about 1.1.2 and 1.1.3 OTB phones. I'm using an unlocked American phone that was 1.0.2 OTB in the UK, which I've upgraded to 1.1.2.

What's the correct way to go about upgrading this phone to 1.1.3 so I can still have it unlocked?

follow the guides in iclarified.com.
his guides are step by step and easy to follow.
all the guides u require are their, just look for them.
also remember you have the 3.9 bl, not the 4.6 b.l, follow those.
