The iWrench is certainly a handy way to hold up your phone. Made of plastic (less damaging to your iPhone than a real metal wrench, I suspect) the iWrench clamps on gently to your phone and then holds it upright. The right tool for the right job. Prop up your phone with the iWrench while you call a real handyman to fix your problem, or use it to watch a video about how to DIY the fix and then call a real handyman after you screw it up worse. Just $7.99 from Pkid.
