Recently bought my new running shorts for my next race and found out my iphone4 will not fit in the pocket... like no hope... so I have been looking for an armband case and before I decided on one I thought I would ask if anyone has had any horror stories or praise about certain ones? Only one I have seen is the belkin one which i was not really impressed with. Currently running about 7-10miles on average but plan to continue using it through longer runs. I am a smaller guy so arm size is not an issue.
