This could be another iPhone 4 customization that, oh, well sure to let you forget about the antenna-grip issue. We know that iPhone can be mounted with SLR lenses to shot images and videos the way normal DSLR does, but more than that Vid-Atlantic and OWLE have designed a much iPhone 4-friendly prototype that can get you going like a professional videographer. Note what we say, see the demo video after the break.
Unfortunately, there are still now words on the availability of the new design prototype for iPhone 4. However, seeing the video its totally worth the waits.
