4.12.01 is not a unlockable baseband unless the phone is factory unlocked. If its factory unlocked, the phone will always stay unlocked no matter what. So you won't need to preserve the baseband.
Since the phone has been jail broken before, run tiny umbrella to see which shsh blobs has already been saved. Choose the firmware u want and restore it to that one. Use the latest redsn0w to restore. That way, you won't have to worry about any errors in iTunes trying to restore.
Once you have the phone restored, run redsn0w to jailbreak it.
Which firmware are you wanting to restore too?

However it has already been unlocked by a shop, it is not factory unlocked. also jailbroken.
I dont want to lose this unlock, unless i can restore it and unlock it myself, which i think after researching here, its not possible.
And i have cydia on it, however when i open it, it crashes right away.
I want to restore it to either the same firmware or 5.1.1
Awaiting your replies

I'm sorry, I noted 4.12.01 is a unlockable baseband, my correction it's not. Unless its factory unlocked.
If cydia is crashing, you can re run the jailbreak over the existing jailbreak. It won't damage nothing on your device but fix the crashing issue.
Since apple stop signing 5.1.1, restore your device back to 5.1 preserve your baseband. You can either use redsn0w or snowbreeze to preserve it. It will make it into a custom firmware. I would suggest using the latest redsn0w to restore your device. iTunes acts funny with a custom firmware but its still possible.
I have a factory unlocked iPhone 4 and my baseband was 4.12.01 until I upgrade to iOS 6 and it updated to 4.12 02. But since my iPhone is factory unlocked, I can never lose my unlock. Are you use you not factory unlocked?
Have you ever checked your IMEI numbers on your phone, it will tell you everything about your device. There are many websites that will let you check it for free.

Might I add, do you know of any tutorials?
And let me get this straight for a procedure:
1) Jailbreak it again using .. what program?
2) Save the SHSH Blobs using tiny umbrella.. How?
3) Download the 5.1 firmware
4) Download the latest redsnow
5) Run a custom ipsw (to not update the baseband)
6) Run the phone and go to Cydia
I really appreciate your effort

if its factory unlocked then you can just restore it
