Hi Guys, after spending the whole weekend, I finally managed to jailbreak my first iPhone 3.1.3. This article will explain detailed step by step how to jailbreak iPhone 3.1.3 for beginners.

These are the steps:

1. If you do not have iTunes, make sure that you download the latest iTunes. This program is used to upgrade, downgrade, and restore the iPhone OS.
2. Install this iTunes and make sure that you are able to do the SYNCH between your PC (Mac or Windows) with your iPhone
3. Since there is no proven JailBreaker that is able to completely jailbreak iPhone 3.1.3, so what I did was to downgrade to 3.1.2. You can download from anywhere, for example: Redmond. Make sure that you download the iPhone OS Firmware 3.1.2
4. Before you downgrade to 3.1.2, make sure that you backup all your iPhone data to your iTunes on you PC
5. Click CTRL + Restore on the iTunes.  It will ask you the location of the OS 3.1.2 .psw file.
6. Select that file, and then let it start the restoration, I mean downgrading.
7. In the meantime, you can download the blackrain. This is the core program to enable you to jailbreak your iPhone, in other words, to enable your iPhone to install applications (games, themes, ringtones, or other widgets) from other repositories, not the default iTunes AppsStore.
8. I believe, you will not be able to complete the restoration, as the iTunes will throw the error: 1005. DO NOT worry about it. That’s normal.
9. Now, click the BlackRain executable and let it start the ‘rain’.
10. Let it finish the whole set of tasks, and at the end, your iPhone is now already in 3.1.2 OS.
11. Now, click the BlackRain again, to do the actual Jailbreaking.
12. WOW, I believe now you should be able to see this image on your iPhone upon rebooting
13. 
14. Then, DONE

Now, start the downloading

1. Click the blackra1n icon on your iPhone
2. Let it start installing the installers.
3. You can start with  Cydia and Rock. These are just repositories utilities  which allow you to browse through the free apps and commercial apps

Now, enjoy your new JAILBROKEN iPhone.
