While many of us enjoy pitting PC’s against our beloved Apple products, Microsoft Live Labs has given us our first iPhone App.

I decided to check out the app. Since it was the software giant’s debut in the App Store and the program has yet to be released for any other mobile devices, I was especially eager to try it. Seadragon Mobile is the technology that backs Microsoft’s Photosynth.

The application allows users silky smooth zoom-in capabilities into giga-pixel images without having to download the file they are viewing.

The App is great — it gives me cause to look forward to forthcoming Microsoft contributions to the iPhone.
