Although I don't often use tripods, I always have one or two stowed away for special occasions -- including one suitable for my handset. Joby's GorillaPod tripods are a cute, bendy option -- light to carry and bendable. Coupled with a remote shooting app, you could hook your smartphone in any variety of positions. The GorillaPod range supports everything from mobile devices to full-sized DSLRs.
Price: $19.95 - $99.95
