Phubby - the active wearWrist Cubby / Arm Wallet for cell Phone / iPod / PDA with 'touch' technology
This solves my problem of carrying my phone while walking my dog. If I'm wearing something with pockets, that's great, otherwise the Cubby is quite handy.  I stick my phone in the Cubby, no worry of dropping my phone and I'm able to listen to music on our walk. I have the i-Phone 6.
