Apple News UltraSn0w iPhone Unlock to Support PIN-Locked SIMs

The iPhone Dev-Team is expected to release the UltraSn0w unlock soon which will support PIN-Locked SIM cards, according to MuscleNerd.

"Good news...ultrasn0w is compatible with PIN-locked sims"

"PIN-locked sims require you to enter a code before using it. Some people (often, with corporate phones) are forced to use them"

The Dev-Team is working diligently on completing the unlock. We will inform you as soon as it becomes available and publish a tutorial on how to use it.

Please stay tuned!

This is the low down on our tools for use with the 3.0 firmware from Apple, read the whole post in full before attempting anything. Because of some bugs and unexpected changes this will be a multipart release, starting with the release of PwnageTool for Mac OS X. QuickPwn for Mac OS X and Windows will follow sometime soon, please don’t bug us about it, we are working flat out to get everything finished to release them.

1. GOLDEN RULE: If you are using a 3G iPhone with yellowsn0w and rely on yellowsn0w to obtain cellular service, then you should NOT use PwnageTool right now. UltraSn0w is not included with this release and therefore your baseband will be locked and unable to use an operator other than the official one it was bought for. UltraSn0w will be release via APT (cydia and icy) soon. If you have an original iPhone (1st generation) then 3.0 unlock works with this PwnageTool release.
2. Yellowsn0w in its current form will NOT work with the baseband version that is present in the 3.0 update, you will need Ultrasn0w, which will be released sometime soon, Ultrasn0w will work with all iPhone 3G models (but not 3GS), even ones that were previously unlockable, Ultrasn0w (when available) will be released via APT (this means you can get it via Cydia or Icy).
3. Please read all parts of this post before downloading and using these tools.
4. Read items 1, 2 and 3 again and again.
5. At the bottom of this post are the bittorrent files for the 3.0 capable version of PwnageTool.
6. This app is suitable for the recent 3.0 release.
7. PwnageTool will NOT work for the iPhone 3GS.
8. PwnageTool WILL work for Original iPhone (1st Generation), Original iPod touch (1st Generation) and the iPhone 3G.

Baseband 101

The ‘baseband’ is the generic nickname given to the internal components of the iPhone that handle the phone calls and Internet access. This ‘baseband’ is a tiny and unique independent computer system that runs inside your iPhone, it is separate to the main system that handles the applications (such as email and google maps) and it talks to the main part of the phone over an internal communications network. Think of it like a cable modem or other peripheral that is attached to your home PC that needs occasional updates. When a software update is released and presented to you within iTunes the baseband is sometimes updated (to fix bugs or add new features). The 3.0 update for the iPhone 3G contains such an update, so running the vanilla updater straight away with iTunes will reprogram and update the baseband.

SIM Free/SP Unlocked/Factory Unlocked iPhone 3G

This applies if you bought your iPhone 3G for $$$$$$$. This model of iPhone 3G doesn’t have an Service Provider lock (aka factory unlocked) and you are able to put any SIM card into the phone and get service. Your phone is already unlocked so you do not need to worry about baseband updates, simply upgrade to 3.0 using iTunes and then use PwnageTool to create an ipsw and then use this to jailbreak your phone.

iPhone 2G (1st Generation)

Update or Restore your iPhone 2G with iTunes then use PwnageTool to do the magic, ‘nuff said, you don’t need to worry about anything, the baseband will be unlocked, the phone jailbroken.

iPod Touch 1G (Original iPod Touch)

Update to 3.0 with iTunes and use PwnageTool.

iPod Touch 2G (New iPod Touch)

Sorry, no support at this time within PwnageTool, use Redsn0w for an earlier (pre 3.0) firmware release instead.

YELLOWSNOW 3.0 Beta

As anyone reading this blog must already know, this is the big week where Apple releases their official 3.0 FW to the public (Wednesday), and then the new iPhone2,1 hardware, aka the iPhone 3GS (Friday).

On Tuesday evening (just before the big Apple release) we’ll do a live demo of the yellowsn0w carrier unlock working on official 3.0 firmware. The actual link for the feed will be twittered by @MuscleNerd and also placed here when the feed starts. The demo should answer everything you need to know about the new yellowsn0w. But it’s good news for iPhone 3G unlockers everywhere.

Meanwhile, we’re in the middle of testing our PwnageTool and QuickPwn tools, which will work with iTunes 8.2. The jailbreak of course continues to work on 3.0 for all devices it ever worked on, thanks due the Pwnage 2.0 technique released last summer. Our tools will be released no sooner than the Apple release (just in case!).

P.S. For the new iPhone 3GS, please don’t expect periodic updates about any progress we have or don’t have. Nothing gives Apple the upper hand like someone tweeting or blogging partial hack results. That’s not how cat & mouse is played :) That’s how the cat gets fed.

YellowSn0w win support for the 0.9.7 firmware 2.2.1

The Dev-Team does not play in service after QuickPwn and PwnageTool update, the team updated the YellowSn0w to work with firmware 2.2.1, but not all are flowers in the hacker world, unfortunately it does not unlock the iPhone 3G with baseband 02:30:03.


To achieve the unlock of your iPhone 3G, you should restore the machine with a custom firmware with PwnageTool made to keep the old baseband, and then use the YellowSn0w yes.

iPhone Dev-Team Summarizes Where They're At

The iPhone Dev-Team has summarized where they are at with the unlock: Past, Present and Future.

-----
Past
- As predicted in our beta release post, expanding yellowsn0w from dev team testing to worldwide usage revealed some unexpected situations.
- Thanks to specific feedback from you on our reporting page, we’ve been able to tweak the method by which yellowsn0w injects the unlocking payload. We believe we’re converging on a method that works for most cases.

Present
- The current beta version of yellowsn0w is 0.9.6, available via Cydia. Please refer to our beta release post for more technical info about how to install and use it.
- Although ultimately the payload is the same as in the very first beta, we’ve changed the way that it’s injected into the baseband.
- Although some of you have invested time and energy in coming up with a very specific flow that works for you, the best way to first try 0.9.6 is as-provided, straight out of the box with no special usage around it.
- Please continue to provide feedback on our reporting page so that we can iron out wrinkles.

Future
- One major feature we have left to provide support for is PIN locking. We have dabbled in this a bit and think we have a solution, but want to make that a separate effort from making yellowsn0w work with as many SIMs as possible.
- At that point, we can probably declare yellowsn0w out of “beta” status.
- The “permanent” unlock is still the ultimate goal for some of us. We’d like to break the chain of trust a bit earlier in the boot process (if only for the fun in trying).
