Normally an iPhone is associated with just one iTunes library, and you can only manage your music with that one copy of iTunes. PhoneAble takes your iPhone library key and applies it to any number of other iTunes installations, allowing you to manage your music on whatever computer you happen to be at. It's pretty easy to use.
After you have run the backup in iTunes you need to CLOSE iTunes before running PhoneAble.
Changes in v1.2 Beta:
* Made the locating of the iTunes folder a global function for all the operations, instead of just setting the iTunes key.
