Magnetometer finding its way into next iPhone?

Add "compass" to that list of rumored features -- again -- for the next, still-unconfirmed iPhone revision, alongside video production capabilities, a slide-out keyboard, OLED display, LTE / Verizon support, and EV-DO rev. B (okay, not really that last one). Boy Genius Report has obtained two screens allegedly from an unreleased iPhone OS build that suggest a magnetometer'll be part of the new hardware. Given turn-by-turn navigation is now an option for developers, we'd say having directional support is almost a necessity. Why there's also an option for Kitchen Sink in the image we haven't the foggiest, but we're gonna go ahead and add "holographic plumbing assistant" to that wishlist.
