is there really no way to put my cd's or itunes music library from my imac, onto my bb curve? i'm told the only way is to buy the songs again through something called itunes plus. is this true??
Not true. I find it super easy to sync my music between itunes and my tour. If you search the forums, you will find many creative ways people are syncing their itunes with their bb.
I think all you have to do is convert your songs to mp3 (of course depending on how many songs you want on your berry the "just" could sound over-simplified)
The only time there will be an issue is for songs that were downloaded with DRM. I know that songs purchased recently won't have DRM on them, but older ones might. If they do have DRM on them, the options are to burn them to CD, then rip them back as mp3s, or use the utility within iTunes (there is a per song fee, though).
Other than that, Media Sync should be able to work with your library.
