I use mine everytime I workout, when I mtn bike or road, I just slip it in the back pocket of the jersey. At the gym, I just use seidio holster.
My essential workout apps are:
gymtechnik.com
UltraChron timer
Slacker or Pandora
Sorry, no help on the workout band. Actually, I have a brand new motorola arm band (I think if was made for the iphone) I may be willing to sell. PM me if interested and Ill send a pic.
