How to record on a roller coaster?

Like i want to do a POV with my iPhone. I plan to record on the Titan at Six Flags Over Texas. What should i do to not loose or break the phone, but still record the ride?

Tape the camera to the handle bar i guess

I know it's a bit pricy, and you're gonna look like a goof wearing this on a roller coaster, but try a go pro. Or see if you can borrow one.

There are some cases that have a strap on them. You can strap it around your wrist and then hold it knowing that even if you let go it will not drop. There are other heavy duty options that might be easier. Check out the links!

Get a GRIFFIN Survivor Extreme Heavy Duty Case with a belt-clip, with the clip clip nicely on your shirt armband, take a couple of those kids hair lacky's and thats it

I recommend buying a GoPro, then attaching that to the car. I want to emphasize the fact that it is against park rules to video roller coasters with loose items, as it could seriously harm someone as a high speed projectile.

I use an underwater case for your wallet and put the phone in and record I did a six flags and the operators didn't care because it straps around your neck
