Iris Browser was a web browser for Windows Mobile smartphones[1] and personal digital assistants (PDAs) developed by the Torch Mobile company. The first version of Iris Browser was released in 2008.[2] It is currently one of only three web browsers designed for portable devices which scores a 100/100 on the Acid3 test.[3]

RIM acquired Torch Mobile on August 24, 2009[4] and Torch Mobile spokesman George Staikos has announced that Windows Mobile development will not continue. On August 12, 2010, RIM released the first device featuring a WebKit-based browser for its BlackBerry OS, branding the mobile phone as "BlackBerry Torch".[5]
