itunes linux iphone sync

How can I get iTunes (running in VirtualBox on Ubuntu 9.04) to recognize my iPhone?
I'm new to Linux and am trying to synchronize my iPhone to iTunes using Windows XP on VirtualBox. I enabled USB 2.0 and when I connect my phone, VirtualBox recognizes that the phone is connected, but when I open iTunes, I get nothing. The phone does not appear to synchronize devices. I would appreciate any suggestions on what I should do next. Thank you!
