Hello,
All you have to do to access the same list on your desktop is enter your mDigger account information into the desktop version of mDigger Reader. For instance, if you are using mDigger for Windows desktops, first install the program, then click on the "options and settings" icon (it looks like a file with a "+" on it. An options window will pop up. Go to the bottom item, synchronization account, and click on "change". Then enter the user ID and password (the same you use for mDigger on your iPhone). Then click on "ok". Next click on the "synchronize channels" icon (and make sure you are online). Your list of favorites and feeds will be sent to your desktop.
Hope this helps and thanks for using mDigger.
mDigger Team
