My Glif iPhone 4 tripod mount arrived today. This thing holds the phone snugly, although I wouldn't mount my phone to a mountain bike with it. You can turn the phone sideways, upside down, no worries. The material feels strong and durable. I happily paid $20 to help launch this kickstarter.com project into production. Now that they're selling, the price has to come down before I'd purchase any more. Get it at theglif.com
