iphone4 4.0.2 to 4.1?

[dissizitt]

Just to clarify, I am on 4.0.2 unlocked with 1.59 baseband.
I have saved my shsh on tinyumbrella. (4.1, 4.2.1, 4.2b3)

I want to upgrade my iphone4 to 4.1 keeping my baseband.
If I want to achieve this, all i have to do is use tiny umbrella, click on 4.1, start tss server, itunes, shift restore to official 4.1, and kick it out of recovery?

I just want to make sure, before I lose my unlock.

You are correct. Just follow this tutorial:

(for mac, it's "alt/option" restore)

I'm running JB 4.0.1 on my iPhone 4 and looking to update to 4.1, preserving my 1.59 BB. I'd love to jump to 4.2.1 but really don't want to deal with the tethered JB.

Thanks for the tutorial link, @noiceT, I've been looking for a clean & easy to follow guide to walk me through this process.
