iPhone Transfer Platinum(http://www.iphone-mac.com/iphone-transfer-platinum.html) can help you solve this problem. It is specially designed for iPhone users. It is not only to transfer files to iPhone 4 or new iPhone 5, and also to backup iPhone movies, music, photos, ePub, TV Show, SMS, Contacts, etc. to computer directly, even transfer iPhone to iPhone, iPhone to iPad, iPhone to iPod. It is the ideal iPhone manager to transfer files from computer to iPhone.
You can use "Pwnplayer" by installing it to your iPhone from Cydia. This is an iPhone music player app that acts as an alternative to the default iPod. Once you have jailbroken your iPhone, transfer your songs (over SSH) to any folder in your iPhone. Pwnplayer will scan the whole iPhone hard disk and add the songs to its library.
