iPhone Guru

You can listen to audio on iPhone with your Bluetooth headset quite easily. Just pair your headset with iPhone and tap on the Phone application from the home screen. Next tap Voicemail…in the voicemail menu just tap in the upper right hand corner where you can choose your audio source for listening to your voicemails. After you select your paired headset click on the home button and quickly tap the iPod application. Play a song and you can now hear the audio through your Bluetooth headset - although it does play simultaneously from the iPhone’s built-in speakers…just turn the volume down on the iPhone and increase the volume with your headset and you should be able to hear the music loud enough to warrant putting the iPhone in your pocket so the speaker audio will not be so overpowering to the audio streaming into your ear from the Bluetooth headset.
