Good news here because now you can unlock you iPhone 2G, 3G and 3GS 3.1.3 Firmware with old boot roms, and you can also can keep your baseband during upgrading to the latest firmware which is iPhone OS 3.1.3

In other word, once you are able to jailbreak your iPhone with Sn0wbreeze then you can further unlock your 3G and 3GS using the latest version of ultrasn0w or Blacksn0w because both of them are compatible with the older baseband versions

Before we start to unlock iPhone 3.1.3 3G 3GS with ultrasn0w firstly you need to do the following:

1. Jailbreak iPhone 2G with Redsn0w if yours is iPhone 2G and has not been jailbroken yet
2. Jailbreak iPhone 3.1.2 Sn0wbreeze if yours is iPhone 3GS or iPhone 3G and has not been jailbroken yet
3. Let’s do it

After your iPhone is jailbroken then do these steps:

• Now open Cydia -> Touch Manage -> Touch Source

Disable 3G for T-Mobile users before installing ultrasn0w.

• Tap on Edit > tap on Add And then type when you are prompted to enter url source: http://repo666.ultrasn0w.com and touch on “Add Source”.
• Now search for Ultrasn0w (once the repository added) in Cydia then install it, and this app will do the job to automatically unlock your iPhone
• Restart your iPhone your iPhone 3G or 3GS on firmware 3.1.3 is unlocked now!
• Well done!

Since Dev Team made PWnageTool 3.1 application available to download, now iPhone users can jailbreak & unlock iPhone OS 3G 3.1 using it and retaining their current baseband, and that’s a good news for many people who had accidentally updated to the newest Apple firmware. Now you are current iPhone OS 3G 3.1 is unlock-able and jailbreakable so you don’t need to downgrade your iPhone 3.1 Firmware To 3.0.1 or 3.0.

But unfortunately PWnageTool 3.1 application can be used for Mac OS only and for Windows OS, Dev Team promises to make a new release, so just wait and see and do nothing stupid. This new application was launched yesterday and I see there are many sites have given on how to steps to Jailbreak iPhone 3G on OS 3.1 Pwnage Tool, thus I won’t post about the same issue here, but don’t worry I will point you to their sites so you will be able to follow their steps:

My visitor on Downgrade iPhone 3GS 3.1 to 3.0 OS Firmware asks on what it takes to get him permanently out of recovery mode? This condition usually occurs after jailbreaking or unlocking iPhone, as the result of it, each time we restart our iPhone, it enters in recovery mode, of course this situation can be frustrating because we have to repeatedly typing ./irecovery -s every time in terminal.

What he is currently facing called as recovery mode loop (i.e. your phone enters recovery mode on every reboot). So if anyone reading this post facing the similar situation, follow these guides to get you out from this inconvenient situation.

In this post we are going to use iRecovery, is libusd-based a libusb-based command line utility for Mac OS X and Linux (perhaps Windows too). It is able to talk to the iBoot/iBSS in Apple’s iPhone/iPod touch via USB. (Source: Wikipedia IRecovery)

For Windows users, installing LibUsb-Win32 is required to run iRecovery.LibUsb-Win32, a port of the USB library libusb the Windows operating system. Because it will give permission to user space applications to access any USB device on Windows.

Attention : Before getting started Download this package included iRecovery for Windows & Mac and LibUsb-Win32 Download Here. This process is universal and tested several times though we are not responsible for and damage (if any) use it at your own risk..
