those new "multitasking" gestures unearthed in the latest iOS 4.3 beta, because BGR's got some shots up of an purported internal build that seem to indicate Cupertino intends to push them down to the iPhone line as well. Now, there are a couple of obvious red flags here -- using "four or five fingers" sounds pretty unreasonable for a 3.5-inch display, though it'd certainly tie in with recent rumors that Apple's turning sour on the physical Home button and might indicate that the complete redesign we're hearing about could include a slightly larger display. Of course, it could also indicate that this is really early software with the wrong (read: iPad) wording -- but at any rate, we could definitely see the benefit of, say, a two-finger gesture to swipe between apps.
Now, on to part two: 9to5 Mac seems to have unearthed traces in the iOS 4.3 beta of a new feature called "Photo Streams" that seems to be -- you guessed it -- a way to share continuous streams of photos with friends you approve, presumably through MobileMe (which would fit in nicely with the Find my Friends stuff). Alone, that's not worth $99 a year -- plenty of other services offer similar functionality -- but we wouldn't be surprised if this were bundled in with a bunch of MobileMe refreshes this year.
Update: We just received an interesting tidbit of information on the above pic (and others that BGR has its hands on). According to sources, after the iPhone 4 barroom debacle, Apple made significant changes to how it keeps track of -- and identifies to third parties -- its devices. Namely, the company began adding clauses to screens on the phones which read "Confidential and Proprietary, if found, please contact..." followed by a 408 number (that's Cupertino, of course). This prevents any misunderstanding from parties who may come across these devices. So what does it all mean? Well, not much, save that it seems these photos we're viewing are in fact the real deal... which means gestures may be headed to your iPhone. Intrigue!
