1. yes
2. No.
You dont restore or update to official 5.1.1 with itunes. If you do that you will lose your unlock. You restore to a custom No_bb 5.1.1 firmware that you need to create with redsnow.
3. yes
4. yes
follow this tutorial on how to create a custom ipsw:
Create Custom IPSW For iOS 5.1.1 To Preserve Baseband
You Need:
Download the latest redsnow
Download original IPSW iOS 5.1.1 For iPhone 3GS
Procedure To Preserve Baseband
STEP 1: Download redsnow
STEP 2: Start redsnow and head over to Extras > Custom IPSW.
STEP 3: Select the original IPSW file for your iOS device which you downloaded from the above link.
STEP 4: Redsnow will now create the custom IPSW file, the one that has preserved the baseband meaning you will still be on the previous version (baseband).
STEP 5: Enter into Pwned DFU mood by going to Extras > Pwned DFU. Just follow the on-screen instructions.
STEP 6: Once your iPhone is in Pwned DFU mood, go to iTunes and press Shift+Restore (Windows) or Option+Restore (Mac). You will need to select the correct IPSW file it will have a prefix “NO_BB”.
Then once you're on 5.1.1 with baseband 05.13.04 you JB it with redsnow and install ultrasnow from cydia to unlock.
Let me know how it went.
And you're very welcome bro.
