How to download music on a iphone 3g?
there are several ways you can download and put music on your iPhone 3G
1.-Purchase songs in iTunes directly on your iPhone (this will cost you money and require you to create an iTunes account,if you download apps, you already have one).
2.-Insert a CD into the computer you plug your iPhone to, open the CD with iTunes, and rip the contents of the disc into iTunes (iTunes has a tutorial for this if you need further information), sync your phone with your iTunes on the computer and the songs will be added to your song library in your phone.
3.-You can use a P2P (peer to peer) sharing program ex. Frostwire, Winamp, eMule, to download the songs onto your computer. Take note of what folder these downloaded songs are being sent to. In iTunes, select File>add folder to library, a window will open, select the file where the downloaded music is located, and iTunes will add it into the music library in iTunes. Sync your phone with iTunes and the downloaded songs will be added to the music library on your phone
