version: 4.3.3 (8J2)
Model: MC133PO
Serial: 8801580C3NR
Firmware modem: 06.15.00

I want to ugrade to official iOS 5.1.1 via itunes.

Can I make this without make a "brick phone"


I only want turn it in a official iPhone upgradable via iTunes and I don't need it unlock, because it's already Vodafone native.

Yes, just put it into iTunes and click update

No he has the iPad bb, you need to use sn0wbreeze or redsn0w to make a custom ipsw that doesn't have cydia installed that's the closest you'll be to stock

I have the latest redsn0w version, now I need a ispw, correct?
Anyone tell me a step-by-step procedures?

J03Y4G, are you saying that this phone, with iPad baseband, never more could upgrade via iTunes?

Thanks

He's right, you won't be able to restore using a stock firmware. You have to create a custom one without a baseband

To upgrade:

Download the latest version if iTunes and the iOS 5.1.1 firmware for the 3GS
Create a NO_BB ("no baseband") custom IPSW using redsn0w- open redsn0w, click "Extras", and click "Custom IPSW"
Enter pwned DFU mode- In redsn0w, go back to the Extras menu and click "Pwned DFU".
Open iTunes and hold down the "Shift" key (on Windows) or "Option" key (on Mac) and click on Restore.
Navigate to your custom IPSW (the NO_BB ipsw) and select it.
Then continue with the restore as normal.
