so @$(@ing swaptunes switched my library. Needless to say I didn't know it switched em as soon as you open the app. Anyways how do I switch it back? I don't see a point to the app if I can't get the music back.
after you run the program, open up the iPod app and you will see which library you are in. for example, if you just installed the app, and if you run it, you will see a message saying something to the effect of "swaptunes is swapping your music library". after it says that, open up the iPod app and you will see that you have no music or anything on there. This is when you now want to sync with the second computer.
swaptunes, or actually, swaplibrary has messed up my iPhone twice. i will not install it again as i had to SSH into my phone and manually delete the second library so that my primary one can be accessed again. use this app if you are comfortable with going into your iPhone via SSH and manually deleting the second folder because after a while, that will likely happen.
