Ok so the Dr tells me I have to start jogging or doing some form of exercise if I want to live long enough to enjoy all these tech toys I keep buying. So, I have a regular leather belt case for my X, but I'm not likely to be wearing a belt when I go jogging. What is a good case to use for jogging or exercising (keep in mind I will likely be wearing t shirt, and shorts or sweatpants). I don't want to hold it because I'm afraid I'll get sweaty and accidentally drop the phone. I'll be using the X to stream pandora or listening to MP3's while jogging and incase I get called by work (I'm on call 24x7). Thanks!
