iPhone iPhone 4 on 4.3.3 trying to upgrade to 5.1.1

Hey guys, I've been trying to upgrade to 5.1.1 from 4.3.3 while preserving baseband. I am on jailbroken 4.3.3 and want to upgrade to 5.1.1 jailbroken. I am using gevey to unlock my phone at the moment. I have made a custom IPSW using redsnow and snowbreeze and I get error 3194 when trying to restore using both of the custom IPSW. I have edited the host file, when I delete everything apple related I get the 3194 error, when I leave only "74.208.105.171 gs.apple.com", I get error 1604. Im stuck and dont know what to do. I baught a IMEI unlock but I'm not sure if the seller is reliable so I want to preserve baseband just in case. IMEI requires you to restore and I just feel helpless

Do you have shsh blobs saved for that i4 for iOS version 5.1.1?
If yes did you stitch those blobs to the custom ipsw you created? Did you put your iphone in pwned DFU before trying to restore to the custom no_bb 5.1.1ipsw with the stitched blobs?
If you missed or not sure about any of that stuff then it wont work.
If you bought an imei unlock for it and the seller said its done then good chances are its unlocked now.
You can always install SAM from cydia to deactivate the phone and then plug it to itunes to activate it again to see if it gives you the congradulations your iphone is unlocked message.
Have a happy new year.

Thanks for the fast reply!
I do have the shsh but I dont know how to stitch them to the no_bb IPSW.
Can you help me with this?
& yes I pwned DFU before I tried to restore to no_bb

Yes, you just open up the latest redsnow again and go to extras/even more/restore/ click ipsw and select the 5.1.1 firmware and then right below it says blobs. Select "use remote blobs for restore" and it will pull them for you automatically from cydias blob server and create the custom 5.1.1 with those blobs unique for that iphone 4.

You are awesome! I am on 5.1.1 and the IMEI is working just fine! Now I can use redsnow to jailbreak correct?

For everyone stuck on 3194 or 1604 error try creating custom IPSW with redsnow and stitching the shsh blobs to the custom IPSW you created, all in redsnow.

Now I just need to do this to my moms phone but Im having trouble with the 3194 again
I couldnt stitch the blobs because the phone didnt have blobs for 5.1.1 on Apple or Cydia servers.
I put the phone in pwned DFU and try to restore to custom IPSW and I cant do it. She has a new bootrom 3gs on 4.1 jailbroken.
