Currently I still have an iPod Touch and nano (which I actually only use to run). The Nano is pretty small and fits closely into the pocket, if I now introduce the iPhone with the Touch respectively run to go is to me the inevitable question is whether this is at all practicable. In itself, I could just get rid of the iPhone a lot of technology "(mobile phone, nano, touch) Are there any armband for iphones? Also if you know which is a good headphone while running? Any help is appreciated.
