yes on your phone go to the dialer pad, and enter this, ##872#, then connect it to the 360 or computer and you will be able to recieve calls when connected.
out of curousity where do you guys get these code/numbers? and btw my phone doesnt sync after i hit that =(
The codes are posted around the forum.
Also that code turns your phone off of mass storage or usb mode so thats why it no longer syncs, although it should still be charging. You cant use your phone and access ur files through a computer or 360 at the same time.
Edit - apparently i was incorrect you can sync at the same time. But I havent tried it myself just going off of the posts below.
