I had 1 for my hd, loved it. So got 1 for hd2. Saw 1 with 3.5mm headphone jack, super for listening to tunes,& charging. But, Didn't realize that unless plugged into external speakers when charging ,say at nite, you won't hear phone ring, or message alerts? So, I just plug into reg. charger,so I can hear ring, its my only phone. Might be getting reg.1?
Edit; it does still work to charge spare battery.
Just had thought? If I take out the 3.5 male plug, it will work like I need it too! Right?
