CollabraCam: CollabraCam links video from multiple iPhones and feeds them into another iPhone that controls live, multi-cam editing. Utilising a wireless LAN to get all the phones networked, the idea behind CollabraCam is that minimal-if any at all-post-production is necessary. $7.99
RecognizeMe: RecognizeMe, a new jailbreak app, uses your iPhone 4’s front-facing camera to scan your mug whenever you want to unlock your phone. Is it as discreet as tapping to enter? No-you probably couldn’t subtly scan your face at dinner for some mid-meal texts. But it’s surely a hell of a lot more secure, assuming you don’t get sucked into some sort of Face/Off terrorism scenario. Jailbreak app.
