its not the d3 its the iphone! Its the way that the software was coded, no activity for any program while not on the screen. Just using my jawbone alone it unpairs after 15min of inactivity. look out for it next time while browsing through the phone; turn on your earpiece and goto phone, you will see in the top right corner the BT icon blue, but hit the home button and its grey again, also, goto ipod, its greyed out. Thanks apple!
