I hear that the iphone syncs well with the 09 cobalts equipped with the bluetooth/usb option, but has anyone used any of the HTC smartphones with the cobalt. Im getting a Tombile Mytouch 3g and was wondering how it would talk to the car connected thru USB

 

Not sure about that particular phone but I have an HTC Touch Pro from Sprint. On mine, under start, settings, connections, there is an icon for usb to PC. There I can select Disk Drive option which allows the phone to connect to my usb and play MP3s from my phone.
