I recently picked up a galaxy s2 from t-mobile and noticed the flash is below the camera.
When looking at accessories online, it seems most sites offer backplates designed to have the flash next to the camera. A quick google image search for 'galaxy s2 flash' found me a webpage describing the difference between the galaxy s2 and the s2 skyrocket- with a few differences including the flash.

Namely, I'm looking for a nice big extended battery that's compatible with a beefy case for when I drop it... I've found a few good looking batteries, but not any cases to fit the extended backplate. Most of the batteries I find are for a flash next to the camera...

Any real explanation of what I'm dealing with would be great!
