I My old htc and earlier phones with android had mass storage. The reason i want it so bad is that my car has ford sync and with ums through usb, i can verbally select tracks i want played without looking at the phone. Bluetooth works but i have to look down at the phone to change songs. Also with old versions of android i could get the stereo sync system to read back my texts and i could verbally send texts also. It was awesome. Iphones work perfectly but i hate iphone. Android worked until icecream sandwich. Its a huge loss for people with stereo systems that have verbal command control across all makes of cars.
