Take it from someone who knows: Photoshop can be used for both great good and great evil (three words: Fake. Celebrity. Nudes.)
The above gallery falls somewhere in the middle. It's various "artists renditions" of what the upcoming iPhone 4G might — or even should? — look like.
Common themes? A return of titanium in some or all of the body construction. Lots and lots and LOTS of storage, with no "faux-totype" offering less than 32 gigs. After that, it's an industrial design free-for-all: Big honkin' cameras. Body curves tinier than Megan Fox's corseted waist in the JONAH HEX movie. Slide-out keyboards (which kinda, y'know, defeat the whole touch-screen concept, nu?). Even a crystaline body that wouldn't be out of place on the set of MINORITY REPORT. Often impractical, all fanciful.
Then again, a hacker can dream, can't he/she?
