Hey guys, I am new to the forum, so I apologize in advance if someone has already posted something like this. I will be going skydiving in the next few weeks for the first time, and I want to film all of it from my iPhone 4. My question is, is there a wrist band accessory to keep my iPhone from leaving me while in freefall? I need something that would be tight and would 100% not come off during freefall. Any help would be greatly appreciated! Thank you!
