Other projects

In the first decade of the 21st century, Johansen's career has included many other projects.

2001

In 2001, Johansen released OpenJaz, a reverse-engineered set of drivers for Linux, BeOS and Windows 2000 that allow operation of the JazPiper MP3 digital audio player without its proprietary drivers.

2003

In November 2003, Johansen released QTFairUse

Although these resulting raw AAC files were unplayable by most media players at the time of release, they represent the first attempt at circumventing Apple's encryption.

2004

On April 25, 2004 Johansen released yet another program: DeDRMS. Written in C#, this 230 line program also removes copy protection.

On July 7, 2004 he released FairKeys, a program that can be used to retrieve the keys needed by DeDRMS from the iTunes Music Store servers themselves.

 for the iTunes Music Store blocking the use of his PyMusique program. The same day, an update to PyMusique was released, circumventing the new patch.

On June 26, 2005, Johansen created a modification of Google's new in-browser video player (which was based on the open source VLC media player) in less than 24 hours after its release, to allow the user to play videos that are not hosted on Google’s servers. The significance of the modification was exaggerated by the online media.

In 2005, Johansen worked for MP3tunes in San Diego as a software engineer. His first project was a new digital music product, code-named Oboe.

Sony BMG DRM rootkit

In November 2005, a Slashdot story notes that Sony-BMGs XCP DRM software includes code and comments (such as "copyright (c) Apple Computer, Inc. All Rights Reserved.") illegally copied from an iTunes DRM circumvention program by Jon Lech Johansen. A popular claim was that, using the criteria that RIAA uses in its copyright lawsuits, Johansen could sue for billions of dollars in damages.

2007

In July 2007, Jon managed to allow the iPhone to work as an iPod with WiFi, without AT&T activation.

2008

On February 2, 2008, Johansen launched doubleTwist

, which allows customers to route around digital rights management in music files and convert files between various formats. The software converts digital music of any bitrate encoded with any popular codec into a format that can be played on any device.

2009

In June, he managed to get an ad for his application doubleTwist on the wall of the
BART exit outside of the San Francisco Apple Store, just days before the 2009 WWDC event. On June 9, it was reported that the ad was removed by BART for allegedly "being too opaque" (the background was blueish) and not allowing enough light into the adjoining transit station. The ad was later redesigned and redeployed with a transparent background.
