This is a project I did with my friend Marcus Tiplea ( check his profile on dribble http://www.dribbble.com/vectink ) who did the design and I modeled the phone and rendered it.
Hope you enjoy it.
Edges look kinda sharp, screen color looks a bit washed out.
I kind of actually like how the corners are sharp. Too many smartphones fit into the generic iphone rounded rectangle cookie cutter. There does seem to be an apparent lack of speaker on your model, is it located on the top edge? Have the acoustics of placing the speaker on the top edge been considered?
