The Dev Team have released yellowsn0w with the ability to unlock the latest 3G iPhone Version 2.2 running Modem Firmware 02.28.00.

(Details Below)

BASICS

• The unlock about to be released works exclusively with baseband 02.28.00. This baseband is provided by the latest firmware update (2.2) from Apple.  You’ll need to upgrade to this release using iTunes and then use QuickPwn to activate etc. There are plenty of tutorials about this on hackint0sh, iclarified, bigboss, and other established tutorial sites.  Because it works on 02.28.00, it is available to everyone on the planet.  This means we don’t need to unnecessarily expose holes in earlier basebands, which is an important concern.
• The application is a small daemon that is launched on boot.  It injects the payload at boot and also whenever there is a baseband reset.  You won’t notice anything about it other than that your third-party sim now works.  It’s a small program and unobtrusive.  There is no GUI (this is by design).
• You can add the application using the sources outlined below (coming soon). There are Cydia and Installer sources available, so use whichever you are comfortable using.
• yellowsn0w is completely removable through Cydia, the command line, and iTunes.

DETAILS

• There is a known issue with SIM cards that have STK (SIM Toolkit) application menus.  These menus are usually items such as “top up” “get credit” etc. These menu items confuse the application sometimes.  Removing and reinserting the SIM once after reboot (give it about 10 secs after you see the slide to unlock widget) fixes this issue.  We’re working on a better fix.
• For those of you using SIM cards without STK menus, the application has some optional arguments that will make the unlock much faster for you.  So either experiment on your own (use “yellowsn0w -h” for usage) or wait for a customization writeup.
• After you install yellowsn0w via Cydia, you should return to the Cydia main menu then reboot your iPhone with the 3rd party SIM installed.  Wait for the slide to unlock screen, then wait 10 or 15 secs more.   If you don’t see your carrier name pop up, then remove your SIM, reinsert it, and wait 10 secs more.  This is the step we’ll be working on eliminating next.

RANDOM

• The application is version 0.9.  This is considered beta software, you use it at your own risk. You know the score.
• The application is released on a non-commercial basis.  Please do not accept pirates and scummy ripoffs of this software. We license this software for single use and in a non-commercial environment (meaning you can’t charge for it). The techniques and methods used are not to be used by third party companies. We are watching you Jody…we won’t be so forgiving this time.
• Direct linking to the repository URLs is prohibited, please only link to this post. We will be checking referrers.

The iPhone 3G is used all over the world with all sorts of SIM cards, and we almost certainly will see untested and unexpected situations.  If the soft unlock doesn’t work for you on day 1 (literally day 1, of 2009!) then please don’t panic or be impatient.  This is new territory for everyone, so enjoy the ride as much as you can

The Dev Team are aiming to do the live demo in about 12 hours (3PM EST).  The actual URL will be tweeted via MuscleNerd’s twitter account just as it starts.

MuscleNerd will be using Qik to broadcast a live video and audio stream (from an iPhone 2G) of an iPhone 3G being soft-unlocked with yellowsn0w.

UPDATE 1 - 1:45PM EST/7.45 CET

UPDATE 2 - 3.13PM EST/9.13 CET

We just wanted to inform our fellow readers that the hyped venezuelan 3G unlock is a bad joke, fake, troll attemp (or what your like to call it), don’t use any of the files in the archive, it might even contain malicious code.

Why it’s a bad fake?

The only way to break 3G is find a exploit which enables us to be able to write to baseband and alter it towards a unlock.

There was said you can install unlock via bootneuter. Bootneuter is designed for 2G baseband and it’s bootloader, it’s technical impossible to have it work on 3G. XGold != SGold2. Altering the baseband on 3G via bb bootloader (like our fellow neuter does) is not possible on a XGold chipset enabled phone like the 3G. They have a very secure and unbreakable way of updating, not even flashing routines are included within the baseband for security reasons.

Other than that, the included ipsw (made with pwnage) is even for a 2G phone, not a 3G .. complete techincal understandment fail.

That blog, which is spreading this news, is talking complete bullshit. Still we have no clue what the sense of this fake action is, other than trolling the hoping iphone community, but it might be even a bad attemp to spread malicious altered files. A investigation of this pile of crap for signs of evilness is still undergoing.

What this set of files is or should be, noone knows, but it is for sure no unlock. If you are really going to force stuff this in your 3G on some stange way (not thinkign you will ever suceed) you might be sitting there with a really fucked up device in the end. Please be cautionous with handeling these files, you have been warned.

Update: Seems The guy who made this fake is upset upon the early unmasing and likes to spam our comments with serval diffrent names in spanish and translate-english.  Please, at least change your IP before using other nicknames if trying to fool peple on a hacking board. If you try to play the Z game for the donation $$…YOU FAILED, hey he at least had something working, even if it was stolen. Please keep this in mind John, Alfonzo, Michael or what your name really is.
