The Carrier Unlock for the iPhone 4 is something that lots of people want, mostly because they want to use their new iPhone 4 in different countries. When you travel, instead of racking up large roaming charges just to use your iPhone 4, you can instead buy a local pay as you go SIM. You pop it into your iPhone 4 and you’ve got a local phone number and can make free local calls.
Recently the Unlock for the all of the available 3G/3GS Baseband’s was released. Which now provides loads of people the choice of changing carriers or using a pay as you go SIM when travelling.
The iPhone 4 is a different beast however, and this is why there isn’t an Unlock available at this point. Even though Geohot has posted on Twitter that he has an unlock called iPwn that unlocks all devices for life, and he won’t be releasing it anytime soon. You can read the article at redmondpie.com
The infamous iPhone hacker George Hotz (aka Geohot) is in France these days, taking part in Nuit Du Hack conference which is currently being held in Paris. During his presentation at the conference, he mentioned that he has found a new bootrom exploit, which can ultimately pwn all iPhones for life, including the yet to be released iPhone 4. He has named this exploit as “pwned4life”.
He’s referenced the iPhone 4 and Jailbreaking/Unlocking in his tweets recently.
@comex not sure why you wrote I am about to release. like you, I don’t even own an iphone 4. [Tweet Link]
I realize most of you aren’t dicks. I have some cool stuff planned, but not the time to make it how I envision it now. Keep an eye on spirit [Tweet Link]
As you can see, right now its not Geohot’s priority to do anything about the iPhone 4 Jailbreak/Unlock. However he has somethings in store.
Here is some more information that the iPhone-Dev’s have discovered.
The DevTeam and others have been checking through the iPhone 4, and have noticed the baseband runs a completely different OS than on previous models. The iPhone 3G and 3G[S] both ran Nucleus OS on the PMB8878 baseband CPU (aka XGold 608), where the iPhone 2G ran the PMB8876 (aka S-Gold 2). iPhone 4 uses the PMB9800, or X-Gold 618 – running a separate OS – ThreadX, an RTOS by ExpressLogic.
So now we just wait, as the iPhone 4’s make their rounds to all their owners in different places. We should see more news about the iPhone 4 unlock/jailbreak.
