Air Sharing Pro
The closed nature of Apple media devices regarding file transfer is problematic. Air Sharing Pro gets around any restrictions by turning your iPhone or iPod touch into a wireless drive that you can access from your Mac or PC.
Connecting is easy, and the app supports viewing many document types, also offering a selection of tools when browsing files (move, copy, zip, etc).
Although we’ve heard complaints about Air Sharing Pro’s PDF support, we found it fine, though not as robust as a dedicated reader.
The only negative we unearthed was Air Sharing Pro using a third-party server as the means to email. Also, if your demands are light the £2.99 standard Air Sharing might be enough.
A great way to turn your iPhone or iPod touch into a wireless drive, and good for viewing various document types.
