Air Sharing is an application that lets you use your iPhone as a file store and document viewer. You can connect to your phone from any Windows, Mac, or Linux computer that is on the same network.
Air Share, like the previously reviewed Data Case allows you to connect from your computer and store files on your iPhone or iPod Touch. Air Sharing works very well. I've tested it both from Windows Vista and OSX. Both computer had not problem connecting to the iPhone, adding, or downloading files from the device.
The integrated viewer will allow you to view, but not edit, a large variety of document types including: All Microsoft Office and iWork documents, HTML, PDF, RTF, and a large number of source code files. The reader could use some enhancement though. With screen space at a minimum it would be nice to turn off the top and lower navigation bars at least when not in use.
Supported File Viewer Formats
iWork (Pages, Numbers, and Keynote), full resolution if saved with preview Microsoft Office (Word, Excel, and PowerPoint), with limited support for XML formats Web Archive (web-page downloads packaged by Safari) Web page PDF HTML RTF (Rich Text Format) RTFD (TextEdit documents with embedded images) Plain text (many different file extensions), with Unicode support Source code (C/C++, Objective C/C++, C#, Java, Javascript, XML, shell scripts, Perl, Ruby, Python, and more), with color-coded formatting Movie (standard iPhone formats: H.264, MPEG-4, 3GPP, etc.) Audio (standard iPhone formats: MP3 VBR, AAC, Audible, Apple Lossless, AIFF, WAV, CAF, etc.) Image (standard iPhone formats: GIF, PNG, JPG, TIFF, etc.)
If you have the need for a mobile document reader -- or a memory stick replacement application, this is a great option.
