WIKiPhone complete guide to unlocking iPhone OS 3.1.3

I own a 1st generation iPhone I bought nearly 3 years ago and it still runs awesome and have purchased 10 iPhones (3G/3GS) off eBay for many of my friends. My buddies proudly call me 'The Unofficial Apple Marketing executive'. Something to be really proud of eh ?

I'll outline below one of the most popular and easiest unlock + jailbreak of iPhone OS 3.1.3 (All generations):

Please note that this unlock will only work for 04.26.08 baseband. Anything above and you would need to wait until a few days after June 22. That's when OS 4.0 is slated to be released and by then the awesome hacking community should be ready with a working unlock of all bootrooms/basebands on OS 4.0 and below.

You can check your check your baseband (Modem Version) under Settings>General. In the below screenshot you can see the baseband is 2.28.00

Warning: Please stop here if your baseband is anything greater than 04.26.08. iPod Touch users can proceed below.

Download and install the latest version of iTunes from Apple

Step 1. Download sn0wbreeze here.

Step 2. Start Sn0wbreeze and select “Simple Mode”.

Step 3: Sn0wbreeze will now ask you to browse for your .ipsw file. Select the correct 3.1.3 firmware .ipsw file by clicking the “Browse” button. Sn0wbreeze will verify the selected file and then will present you with following screen.

Step 4: Click on "Yes" when Sn0wbreeze asks you “Do you want to activate your iPhone?” for hacktivation. Click on “No” only if you are on an officially supported carrier like AT&T.

Step 5: Sn0wbreeze will now create the custom .ipsw file for your iPhone which will be jailbroken.

Step 6: Now you will have to restore your iPhone to this custom firmware 3.1.3 that you just cooked using Sn0wbreeze for your iPhone. Click on your phone from the sidebar in iTunes and then press and hold left “Shift” button on the keyboard and then click on “Restore” (Not “Update” or “Check for Update”) button in the iTunes and then release the “Shift” button.

This will make iTunes prompt you to select the location for your custom firmware 3.1.3. Select that custom .ipsw file and click on “Open”.

Step 7: Now sit back and enjoy as iTunes does the rest for you. This will involve a series of automated steps. Be patient at this stage and don’t do anything silly. Just wait while iTunes installs the new firmware 3.1.3 on your iPhone. Your iPhone screen at this point will be showing a progress bar indicating installation progress. After the installation is done, iPhone will restart automatically and you should now have a fully jailbroken iPhone running on firmware 3.1.3.

Congrats!! Your iPhone/iPod Touch should be jailbroken now and you should be able to install any application.
