I already had the model with shell for the iPhone 3G. I just was looking for the 'Mount Grip Tight' universal accessory to attach any portable or small camera on the foot that I had. A few euros near the new foot + accessory is not more expensive; so I bought the set. This universal model is suitable both for all iPhone for my Galaxy S3. Perfect for making really still stills (video, photos, documents). The hanging around a bar or a handlebar a little scary, but it holds up. (Do not shake anyway.) I recommend it.
