Currently multiple third party applications allow the iPhone to tether or share it’s data plan with your computer. Just recently I discovered using June Fabrics Technology‘s PdaNet you can not only tether your data plan but also it’s wifi connection, making your ipod touch or iphone also a wireless USB adapter.

Basic steps to use ipod touch as a wireless usb adapter:
-Install PdaNet Desktop. This requires itunes to be installed.
-Install PdaNet in cydia or RockApp. If you don’t have either of these you most likely haven’t jailbroken your iPod… Similar to most useful software on the iPods, you will NEED your device jailbroken.
-On your iPod, set the PdaNet application to USB Mode in the settings.
-On the desktop, right click on PdaNet tray icon and click connect.

PdaNet is also available for Android, PalmOS, Windows Mobile, and BlackBerry.

Anyone who doesn’t plan on using this software also on a 32-bit operating system could install Rosetta Stone in a guest operating system using virtualization software such as VMware or VirtualBox(freeware) and then proceed to copying the contents of the “Application Data\Rosetta Stone” folder back to their Windows 7 install.

If planning to add another language pack later I do suggest backing up the tracking.db3 file considering it stores all the user information. You can manually alter the SQL database using software such as SQLite Database Browser.
