After downloading SharePod, if you have an iPhone or iTouch, simply run SharePod from your computer.
If you have an older iPod (Shuffle, Mini, Nano, Classic), you can run SharePod right from your iPod drive. (The iPod appears in 'My Computer' when docked.)
If you see an error message like 'Failed to initialize: 0xC0000135', you need to download the Microsoft .NET Framework 2. For any other errors, please check the help page before emailing me.
Avoid running SharePod and iTunes at the same time. Neither application will know about changes made by the other, and your iPod could get out of sync with both.
