my blackberry storm armband works surprisingly, the top of it is neoprene so its stretches tall enough to cover the top of the X.
lmao i like how we're all ghetto-rigging our previous accessories to fit this monster.
i'm using a belt clip to secure the x to my waist and using my shorts to cinch the phone so it doesn't fall when i run. it works, haha.
this link for the ebay auction looks promising. i don't like armbands for phones this heavy though...
