UnlockAppleIphone.com – Hackers have successfully cracked the Simlock of the iPhone 3G. After the crack the Iphone can also be used with other telecoms providers than the official suppliers in each country.
The iPhone Dev Team published on the first day of 2009 a 0.9.4 beta test version of the program yellowsn0w a 3G sim unlock application. Iphone users could use this to remove the simlock of the Iphone 3G. Officially, the iPhone is in most countries only aviable in combination with a subscription to one or more specific telecommunication providers.
Cat and mouse
Since the introduction of the first iPhone manufacturer Apple and worldwide hackers play a cat-and-mouse game around Iphone’s simlock protection. So far, Apple updates are often able to undo cracking software, but hackers invent in short time a new trick.
The first generation of the iphone was already cracked, but now also the new iPhone 3G. So-called “jail break” is necessary to carry out the simlock removal.
Variable results so far
Users who have tested ‘yellowsn0w’ report varying results. According to the Iphone Dev developers you should use in any case the latest version (2.2) of the iPhone software before performing the simlock removal process.
More info on yellowsn0w
- 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 QuickPwn to activate etc. Because it works on 02.28.00, it is available to everyone on the planet.
- 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. 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.
