Okay so i ordered a refurbished iphone from ATT (still yet to get here) and i have a few questions about it and if you have answers let me know. 1) when docked do you get the stereo/GSM buzz? (i have a bose ipod dock if that helps) 2)when docked and i receive a call will it play the ring from the speakers or stop the music and use the built in ones? 3) If im watching a video will it interrupt my video for a call? 4) how strong is the vibration? 5) how easily does the back scratch? Even if you can only answer a few of these let me know! Thanks!
