Load music to iphone 4 via itunes?

I'am trying to load music on my iphone 4 that is jail broken and unlocked on ios 5 version 5.1.1 i'am trying to retrieve music from another itunes library which is not the one that i used to jail break and put music on my phone the computerm i'm trying to use is running on the lastest firmware i'm trying not to erase any of my music/pictures or jail break is there any way that i can do this?

To put music onto another iTunes library from different computers - I use home sharing.
Click ITunes --> Advanced --> Turn on home sharing

DO this on both computers.
Once that is done, go to the computer you want the music from and click the library that comes up down the left side. This will show you all the songs from the other computer.
Then you can either drag / import songs from that library into your original iTunes library on that computer.

  • Why won't my music in itunes load when I log in? I'm using my sisters laptop and would like to put my itunes on it. I logged out of her account and signed into mine, but her music still shows up and mine doesn't. How can I fix this so I can sync my iPhone with my music without losing anything?
  • Which apple device can you load your own music? (no iTunes)? I like the iPod touch but all I see is that you have to have music through iTunes. But I don't feel like paying for music. I have my own music but it says I can't load it. I don't want a iPhone. But is there a apple device where you can load your own music?
  • My iphone won't load iTunes or notes? So I click on notes/iTunes and it shows the iTunes background for about 2 seconds, then before it loads, it sends me back to the home screen. I have done a hard reset, and put it on charge until it was 100%, I have downloaded new apps, and my phone is not jail broken, and does not have any sketchy apps or weird Japanese apps - does anyone have any ideas for what I can do to load up these apps?
  • My Iphone won't let me down load a song from iTunes? I tried to buy Taylor Swift's new single, but my Iphone 5 won't download it. It keeps saying error. I have space on my phone, but it still won't load. Any ideas?
