Now that HDR photos (and video!) is the cool kids' latest documenting tool since Hipstamatic, iPhone 3GS owners have been feeling decidedly unhip without the app. It's almost enough for them to resort to film cameras again!
9to5Mac discovered that the SDK suggests that the 3GS actually has the power to shoot HDR photos, as evidenced by the "non-Retina display" icon above. Older models of iPhone are limited by hardware and are unable to take photos using this effect, so there's a good chance that Apple might fire up the high dynamic range switch at some point—if they feel generous.
