Jailbreak iPhone 3.1.3 with Redsn0w 0.9.4

The iPhone Dev-Team has just released redsn0w 0.9.4 to jailbreak and unlock iPhone 2G, iPhone 3G (No unlock for 3G), iPod touch 1G and iPod touch 2G (older Non-MC models only). Do not update to iPhone 3.1.3 firmware yet if you want to preserve your unlock for iPhone 3GS, iPhone 3G, iPod touch 2G (new models) and iPod touch 3G. This is because the new iPhone 3.1.3 firmware updates baseband to 05.12.01 on iPhone 3GS and iPhone 3G which makes it impossible to jailbreak and unlock iPhone 3GS and 3G.

Follow the simply step by step instructions below to jailbreak and unlock iPhone 2G, jailbreak iPod 1G/2G (older models only) on 3.1.3 firmware. You can also jailbreak iPhone 3G with redsn0w 0.9.4 but doing so will make you loose your unlock.
Note: In this guide I have used redsn0w 0.9.4. If this version gives you problem on iPhone 2G and iPod touch 1G, then try redsn0w 0.9.3. Download redsn0w 0.9.3 from here and then follow the instructions as follows.
NOTE: The instructions posted here almost similar to the one we posted earlier with redsn0w 0.9.3 for iPhone 2G and iPod touch 1G/2G. The only difference here is that we are using the latest redsn0w 0.9.4 from Dev-Team which is specially released for this firmware update.
Step 1: Update to original iPhone 3.1.3 firmware via iTunes. Downloading and installation instructions for iPhone 3.1.3 firmware can be found from here.

Step 2: Start redsn0w 0.9.4 and point it to the respective original iPhone 3.1.2 firmware to proceed. Yes you need to point it to iPhone 3.1.2 instead of 3.1.3 because redsn0w 0.9.4 is still unable to validate the latest firmware.

Step 3: Now select “Install Cydia”, “Unlock” and “Already pwned” options for iPhone 2G.

Step 4: Now make sure your device is both OFF and PLUGGED IN to the computer before you click “Next”.
Step 5: Connect your device in recovery mode by pressing the Power and buttons continuously.

At this stage you will be presented with a screen where you will have to quickly hold “Power” button and then while holding the “Power” button, you will now have to hold “Home” button too. Now after few seconds release “Power” button but keep holding “Home” button until installation begins.
Step 6: Sit back and enjoy while redsn0w will do all the rest for you. Once done, your iPhone 2G will restart automatically and you will find it jailbroken with iPhone firmware version 3.1.3.
Unlock for iPhone 2G Only
Step 7: Once you are done with the jailbreak, you can now unlock your iPhone 2G running jailbroken firmware 3.1.3 by using BootNeuter app from Cydia. Follow the instructions from Step 4 here to unlock iPhone 2G on 3.1.3 firmware.

One-Third Of iPhones Used in China Are Jailbroken [Report]

Chinese statistics company UMeng recently published a report on iOS usage in the country, and the standout stat is that fully 34.6% of iPhones are jailbroken.

The report is expressed in the below infographic which is unfortunately in Chinese. Our Chinese being a little rusty, we’re grateful to TechNode for their translation with the highlights being:

• Apple’s iPhone 4 accounts for 54% of iPhones, with the 3GS taking 2nd place with 16.1%.
• 34.6% of iPhones are jailbroken.
• Interestingly only 27% of iPads are jailbroken

The jailbreaking figures actually make sense. Jailbreaking iPhones to unlock them would be of interest to many, whereas the same unlocking requirements don’t translate to the iPad so much.
We also don’t know these figures for any other country for comparison, though we somehow doubt many other countries come close to the 34.6% figure.
