Dev-Team Releases iPhone 3.1 Jailbreak

Here we go again. With Apple's release of iPhone OS 3.1 the iPhone Dev-Team has been busy getting jailbreak and unlock solutions ready. The first of these software packages is Pwnage Tool 3.1 for Mac OS X.

pwnage 3.1 mac

The current version is available directly from the iPhone Dev-Team and supports the first generation iPhone and the iPhone 3G. The Dev-Team is still working on software for Windows and the iPhone 3GS.

As we've seen before, the Apple iTunes 3.1 update for iPhone 3G will change the baseband version on your iPhone, making an unlock impossible with current versions of ultrasn0w.

The Dev-Team has noted this is also the case with the iPhone 3GS:

If you want to keep the jailbreak or unlock on your 3GS, you should resist all urges to install Apple’s official firmware updates without knowing if a jailbreak exists for that version yet. Unless another (different) bootrom exploit is found for the 3GS that doesn’t require a “foot in the door” with a signed official iBoot, then accepting official updates willy-nilly may cause you to be cutoff from the jailbreak. And it will definitely cause you to be cutoff from the carrier unlock.

That being said, there are very specific instructions when jailbreaking and unlocking the iPhone 3G with Pwnage Tool 3.1. The Dev-Team notes the following details:

GOLDEN RULE: If you are using a 3G iPhone with ultrasn0w and rely on ultrasn0w to obtain cellular service, then you should only upgrade to 3.1 with a PwnageTool created .ipsw. - Stay away from Apple’s direct updates as described here and here please get up to speed on the whole subject by reading the information contained in these posts.

If you have an original iPhone (1st generation) then 3.1 unlock works with this PwnageTool release. iPhone 3G users upgrading to 3.1 will need to continue using ultrasn0w with a PwnageTool created 3.1 .ipsw

Pwnage Tool 3.1 for Mac OS X will only work on the original iPhone, original iPod Touch and iPhone 3G. As always, backup your data before jailbreaking.

Dev-Team also notes a cosmetic bug that may occur after unlocking the iPhone 3G:

Unlocked users on the 3G will probably notice that the name and/or logo of their carrier is missing, but they still have full bars and a signal. So far this seems to be purely a cosmetic issue and it doesn’t impact your signal or coverage. We hope to have this issue “fixed” when we release the 3GS compatible version of PwnageTool.

Remember, you may violate the terms of your Apple warranty or your carrier's terms of service when jailbreaking or unlocking.


I am completely new to cell phones and the like, have read for several weeks, all day long on iphone jailbreaking. I just purchased a 3.01 3G iphone, never modified.

I have a question I know has been asked, but the answers I've seen are less than explainatory or detailed.

Here it is:

I know that if you jailbreak the phone, you can then install games, and some non-pay apps, well and good. But for your iphone system and it's functioning, what are the real benefits, other than tethering say, to jailbreak?

Thank you much for any informative replies.

Well you can install games and apps, paid or free, without having to jailbreak via the app store on your iPhone. What jailbreak does is enable you to have complete customization of your iPhone. There are tweaks and hacks that can really give your iPhone the full potential that you wouldn't otherwise see with a factory defaulted iPhone. With jailbreaking you can keep running apps in the background after you've closed them. Or customize your home screen to have wallpaper, change how the icons look. Most people have jailbroken their phones to enable video capture long before apple brought to the 3G[S]. And most people I would imagine will still jailbreak the iPhone 2 and 3g phones for that among and endless list of tweaks and hacks that you can't get from the apple store of a unjailbroken phone.

I hope Dev Team will start working on 05.11.07 baseband (5.09 bootloader)
unlocking for those who upgraded their 3G iPhones to 3.1.
