The iPhone 4 is already blessed with one of the best 5 megapixel HD (720P) cameras on any modern smartphone and the built-in accelerometers and gyroscope make its stabilization capabilities really shine. The iPhone's sleek and slippery profile, however, makes it difficult to manage. The OWLE BUBO camcorder mount (US$169) acts like a harness, provides a way to mount 3rd party lenses and microphones. Anyone thinking of broadcasting from the iPhone 4 should consider this rig and all the expansion it offers.
