The only reason I still JB my iPhone is for volume boosting. I know that 5.1 (finally) fixed/amplifies the volume for iPad's, is this the case with the iPhone 4S? Thanks! Again, to clarify the issue, this is with regard to A2DP bluetooth stereo and in some instances wired headsets, not the built-in speaker. I would also appreciate productive commentary and not sarcasm as one member has derailed a helpful thread into (once again) a juvenile tirade on MacRumors. Thanks!
