[JWiPhone]

1.) Incase Slider
2.) Otterbox Defender or Speck Tough Skin Case, for outdoor activity
3.) Holster, that also holds the iphone wearing a case
4.) Protective Screens
5.) MicroFiber cloth for cleaning
6.) External battery backup
7.) Ziplock bag (thanks also to Hawk)
8.) Stand or cradle to hold iPhone, at first I didn't think it was necessary but I sit in front of a desktop computer a lot and having the iphone sitting in a stand makes a huge difference rather than having it lay flat on the desk.
