Three months after being booted from the App Store for employing, "iPhone volume buttons in a non-standard way," the popular Camera+ app is once again for sale—volume-button functionality and all.
The original version of Camera+ was, of course, pulled for including an "easter egg," unlockable by the end user, that allowed the program to trigger a shutter release via the phone's external volume buttons—a feature that also mimicked Apple's as-of-unveiled virtual shutter button. Camera+ has been resubmitted and does include the same taboo feature, but since Apple has recently implemented a similar technology, the prodigal app has been re-approved. Its latest version, Camera+ 2.4, includes auto-stabilization, one-touch exposure and focus, and 6x digital zoom in addition to the fast-snapping capabilities of shoulder-mounted shutter releases. It's currently available through iTunes for $1. [iTunes via Cult of Mac]
