I need a good armband for an Iphone 4?

I'm going to start running this summer and need one that will protect my phone from moisture but still be able to listen to music. I've been looking for one but still can't find one.

Added (1). I also want it to track my runs

Added (2). Seriously! I'm not going to running on the roads i'm going to a park or something. I'm aware that it's dangerous to not pay attention not only to me but also to drivers drivers. I just want to see how much I ran.

Try looking for one on amazon c: you'll probably get one cheap and pretty fast.

A good running shop will have them however you might consider trying the first few runs without your iphone. No armband is 100% waterproof and one day it will get wet - and wil be expensive to replace.

If you find that you really need to listen to something as you run (assuming this is what you want the telephone to do) then buy a cheap MP3 player - with a bit of luck a supermarket can do one suitable and with enough capacity (and smaller and lighter than your telephone) for about £10.

If you need to carry your phone to use it to make calls (even in the case of an emergency) then wrap it in a zip lock bag and put it in your shorts pockets - far more water proof (and also uses slightly less energy to carry it this way - but not enough to worry about)

No, you need to pay attention to what's happening around you instead of becoming a road hazard.
