Quick Notes - I have a mac and a new Samsung Vibrant phone. I wanted to sync, download, upload playlist from itunes to Vibrant.
Note - I switched my sd card with Avatar loaded on it to my other 4GB sd card.
If you do this, you will not have Avatar to view!
You have wireless option, bluetooth or wired. I tried wired first.
On Vibrant go to Android Market and search for TuneSync, download on phone. First do the free one. On your computer go to highwindsoftware.com, download application for your computer ie, (host). Choose either windows or mac, depending on your operating system.
You may have to go to your sd settings and check some items like sync now, sync when wired and so forth.
With phone plugged in and both things above done, make sure you have your sd card mounted. Top left of phone you will see your usb icon, pull this down to mount and unmount.
Your phone will see your itunes library, from there you can select which playlists you want to sync.
Now to test to see if your music plays you have to UNMount your sd card. Do this then go to applications, music player and voila!!!!
Any problems, go to highwindsoft.com
Good Luck
