Hello all,

If you can attach anything you want to the back of an iPhone 4 or 4S, What would it be and how will you use it? It can be anything!

For me, it would be a Solar Panel Back Plate... super slim, just enough power to trickle charge. This will help sustain battery life and be Green!

LOL! how would you use it?


But was also thinking something along the lines of audio enhancement. One of my gripes with iPhones are the acoustics... i know they are very tiny speakers/microphones, but to me they could have designed it better if the speakers were actually facing you, not the person next to you. So speaker placement where you actually have 2.0 channels is something I would like to see on the new one.

Has anybody created a Sound Bar for the iPhones?
