I like to use my iphone4 to play music, but have two major complaints: 1) the volume is too high for use in a quiet room! And when i set a volume limit in the settings, i find that i am no longer able to tune the volume as finely as i would like. 2) there arent enough external control buttons! if i play music and keep the phone in my pocket, i cannot control which song is playing without taking the phone out, unlocking it, and using the touchscreen. Almost made me wish the phone had a click wheel on the back or something Any suggestions related to the above? Thanks.
