iPhone 4G/HD pictures claiming to be leaked images of the upcoming iPhone device have been popping up now and then online. But none of us is sure how authentic they are.

Something interesting was found by Engadget today. A device which seems to be the iPhone 4G/HD was found in an iPhone 3G case dropped in a bar.

So, does this look like the real deal? iPhone 4G/HD?

BlackRa1n is said to be the easiest and quickest jailbreak solution so far. But here’s the most important difference between BlackRa1n and PwnageTool:

BlackRa1n requires you to update your iDevice to OS 3.1.2 and then jailbreak it. Which means your Baseband will be updated and would not be able to unlock your iPhone later. PwnageTool, on the other hand, creates a custom firmware which preserves your Baseband from updating so that you may unlock your iPhone later if you want to.

So, We strongly recommend to use PwnageTool if you want to Unlock your iPhone after jailbreaking it because PwnageTool does NOT update your iPhone Baseband.

Here’s a guide: how to jailbreak iPhone OS 3.1.2 using PwnageTool

This Guide is for both iPhone 3GS and iPhone 3G. All steps for both models are same. The only difference is that for 3GS you need IPSW file for 3GS and in case of 3G you need IPSW for 3G to create Custom IPSW from it. Both files are linked in the guide.

IMPORTANT

If you’re still on OS 3.0 or updated to OS 3.1 using PwnageTool which means you’ve preserved you Baseband which means, along with jailbreak, you can Unlock your iPhone using UltraSn0w. On the other hand;

If you bought an iPhone with 3.1.x preinstalled or you have updated your iPhone to OS 3.1.2, you will be able to Jailbreak your iPhone only.

If it’s the first time you’re jailbreaking your iPhone, Be ready to follow directions now to get into DFU Mode.

• You will be asked to hold the home button and the power button for 10 seconds.
• Then, you will have to release the power button and hold the home button for 10 seconds to enter DFU.

If you failed to follow the instruction, it will show you a message asking if you want to retry?. Click Yes.
