ok I didnt know.Thats what always happens.
You have to sync that stuff back thru itunes.
I have the same issue, but when I plug the iPhone back into the computer, it shows that it is full of music (over 20GB) and everything is greyed out and I cannot access it, or even really load anything else in to it. When I hit the iPod button on the phone is says I have no music.
Any ideas?
assuming all of your music is in your itunes library already (as it should be), just plug in your iphone and deselect all of your music for syncing (so it's removed from your phone). sync, so it's removed from your phone, then reselect the music you want to be synced, and resync.
something went screwy somewhere, but instead of trying to figure out why, removing and replacing your music should fix it.
That's the problem, I can't remove the music from the iPhone, it's greyed out and won't let me select it.
I had to replace my time capsule [...] and all my music was stored on the TC. So I don't have e music on another source.
Sorry about that, the music is greyed out when I'm in iTunes and I click on the music tab under the iPhone. ITunes will not allow me to select the music to remove it from my iPhone.
