Para Blaze for iPhone 4S/4
By far the most spectacular looking case I've ever had, It also provides the protection you want, without a lot of added bulk. Comes with 2 screen protectors - one mirrored, one regular. The case elevates the iPhone, if it's laying flat, by about 1mm, preventing scratches. It also elevates the bottom edge and the top edge. The metallic parts look amazing - a lot better than the pictures on this web site.
The Flash does not get affected by this case. Take all the pictures you want.
The only con I can think of - and this is knit picking - is that the corners are only half-covered, leaving the front half exposed.
I ordered THREE (one black, two white) from this web site. The service was excellent - very fast and reliable.
