Instead of just clipping into the iPhone 4 and 4S' dock connector—which would have eventually guaranteed a shattered phone—this carabiner accessory comes with longer replacement screws that are promised to securely attach it to the bottom.
So while you can't just pop it on and off without the aid of a screwdriver, it does let you clip your phone to your belt or shoulder strap so it's always in reach. You can even use it as a giant keychain if you don't mind your keys banging against your face when you make calls. The metal plate sits flush enough for most dock accessories to still be used, and for $30 it's just about the easiest way to add a permanent tether to your phone. [Photojojo]
