Microsoft Launches Graphics Viewer for iPhone.

The freeware developed by Live Labs is called "Seadragon Mobile" and lets users view large images on their iPhone with "just a few taps of a finger". It is the first in a series of planned Microsoft iPhone applications and although historically Microsoft and Apple have been market rivals, Microsoft chose the iPhone because of it's popularity and technological capabilities.

The iPhone is the most widely distributed phone with a graphics processing unit, so it was the perfect choice for the new freeware graphics viewer. Seadragon is what powers Microsoft's photo browsing software Photosynth, and works by storing multiple resolutions of a file.

Other software planned for the iPhone for release in the near future includes a voice recognition program.
