Yellowsn0w is out and it’s ready to rock. Here’s how to become SIM-independent.

NB: Install the latest 2.2 firmware before beginning this process.

  1. First, download quickpwn and jailbreak your phone.
  2. Use the latest firmware to pwn your phone (download it from Apple here). This will allow you to install Cydia or Installer. If you just updated your phone or updated your phone on the computer you are running on, you probably won’t have to download the firmware.
  3. Then, add the repositories (DO NOT ENTER THESE URLs INTO YOUR BROWSER per Dev Team’s instructions).
    For Cydia enter: http://apt9..com/
    For Installer enter: http://i..com/
  4. Install . Run it.
  5. Turn off the iPhone and install your third party SIM.
    NB: f you are in the U.S. and are trying this with T-Mobile, you must turn off the 3G switch in Settings.
  6. Turn on the phone. Wait until your carrier pops up. If it doesn’t, take the SIM out and reinstall it.

Keep checking Yellowsn0w for the latest versions of and if you face any issue while unlocking your iPhone 3G.

iPhone 3G has been finally UNLOCKED – But wait… dont download yellowsn0w for another week

iPhone 3G has been finally unlocked by the iPhone Dev Team. The unlocking software is called and runs as an invisible application, and seems to be very easy to install. But the application is buggy and not many have successfully unlocked their iPhone 3G’s. PLEASE DO NOT RUN YELLOWSNOW UNLOCKING APPLICATION FOR FEW MORE DAYS. It needs more finetuning. So wait for few more days.

Gizmodo, reports that while is “very easy to install,” alas “it doesn’t work right,” and takes the Dev-Team folks to task:

Even while this is labeled as a beta, it saddens me that the iPhone Dev Team has embraced the damn beta culture just to make the release on a cute date. It looks like the old days of solid versions are long gone by.

There’s a poll here with people saying if it works or not. At the time of this writing, these were the stats:

It worked: 23 34.33%
It doesn’t work: 44 65.67%
Voters: 67.

Over to the iPhone Dev Team:

We have released the 0.9.1 beta yellowsn0w 3G unlock application.  Please note the following:

BASICS

  • The unlock 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 to activate etc. There are plenty of tutorials about this on 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.
  • is completely removable through Cydia, the command line, and iTunes.

Note – Please report your success or failure here it’ll help the team with the bug fixes.

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” “lotto numbers” etc. These menu items confuse the application sometimes.  Removing and reinserting the SIM once after reboot (give it about 10 secs 60 seconds (with v0.9.1) 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 “ -h” for usage) or wait for a customization writeup.
  • After you install 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 0.9.1.  This is considered beta software, you use it at your own risk. You know the score.
  • The application is released on a non-commerical basis.  Please do not accept pirates and scummy ripoffs of this software. We license this software for single use and in a non-commerical 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 referers.
  • Happy 2009 and enjoy!

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 )

RELEASE INFO

UPDATES

  1. Soon you’ll see 0.9.1 in the repos.  It uses a much longer delay to let your SIM card initialize.  If you have problems with 0.9.0, try this one and wait a full minute after you see homescreen, then reinsert sim card.  We need both success and failure reports to tune this across the world, so please be patient (but please also report result!)
  2. If you are in the U.S. and are trying this with T-Mobile, you must turn off the 3G switch in Settings.  Also if you are good with the command line, you can make it much easier by adding the line <string>-q</string> right after the /usr/bin/ line in /System/Library/LaunchDaemons/org.iphone-dev..plist  (that’s and advanced tip, hopefully someone will make a boosprefs type of tool for it)
  3. No PIN support yet. Remember how we said this was beta?  Well we’re still working out the flow for SIMs with PINs enabled.  Please disable any PIN you may have on that SIM before trying , for now.
  4. The unlock will silently quit on anything other than baseband 02.28.00. It detects the wrong version and just quits to avoid any damage.  Please double check your Modem Firmware setting in Settings->General->About.
  5. For ankle-biters that are pointlessly reversing the application the source is here all open, but remember Jody, we are watching you.
  6. Thanks for the kind words Stephen
