Iphone 4 IOS 5.0.1 unlock??

[coockie_monster]

Hi again,

I have a Iphone 4
with IOS 5.01 (I think)


I live in Portugal, and I can't use portuguese SIM cards (phone was bought in Swiss)
I try to unlock... but I still can't use...


-I try to downgrade software with itunes (edit the host file, use the firmware 4.3.3 etc...)
-But I found errors, like error 2005. So I use a latest version of itunes 10.4.1 (problem solved)
-Then I found another error 1004 and I still can't downgrade firmare



My question is.... it's possible to unlock my iphone?
Am I doing it correctly?


thanks
best regards

How to Jailbreak 5.1 iOS with Sn0wbreeze
Step 1
Download Sn0wbreeze 2.9.2
Download iOS 5.1
Download iTunes 10.6
Connect your iPhone, iPad or iPod Touch to iTunes and backup your personal stuff
Step 2
Run the Sn0wBreeze.exe. Hit Ok, Close Credits and then hit the next button.
Step 3
Hit the Browse button and select the iOS 5.1 IPSW file for your iDevice that you downloaded in Step 1. Sn0wBreeze will identify the IPSW firmware file. Then hit the Next button.
Step 4
Select the Expert Mode, hit Next;
Select General and hit Next;
Make your desired choices, then keep hitting Next until you’re back to the screen where you selected General.
Step 5
Select the Build IPSW option and hit next.
Sn0wBreeze 2.9.2 will start building custom iOS 5.1 firmware to jailbreak your iPhone, iPad or iPod Touch. Sno0wbreeze offers you the choice to play PacMac during the IPSW building process or stick with the Spinner.
Once Done! Hit the OK button. (Custom firmware 5.1 can be found on desktop along with an iBooty folder)
Step 6
Now follow the on screen Sn0wBreeze instructions *important* to put your iPhone, iPad or iPod Touch into Pwned DFU state NOT the simple DFU mode.
Hold Power + Home buttons for 10 seconds
Now release the Power button but keep holding the Home button for 10-30 more seconds
Sn0wBreeze will prompt you once you’re into Pwned DFU state. Your device should now be in DFU mode.
Step 7
Now open iTunes, Hold down the Shift/Option key and hit the Restore button.
Browse and select the custom firmware that we just created, from the desktop.
iTunes will start restoring iOS 5.1 on your iPhone/iPad/iPod Touch. Once done, your iPhone, ipad or iPod Touch will be running iOS 5.1 jailbroken tethered.
How To Tether Boot
On your desktop, there’ll be a new folder named iBooty. Open the folder and run the iBooty.exe.
Select your device from the drop down menu (bottom-right) and hit the start button.
Follow the on screen instructions to put your iDevice into DFU mode.
Hold Power + Home buttons for 10 seconds.
Now release the Power button but keep holding the Home button for 10-30 more seconds
Your device should now be in DFU mode
Once you’re into DFU mode, iBooty will do the rest and your iPhone, iPad or iPod touch will boot into jailbroken state!
