Vietnamese site Tinhte might just have gotten their hands on an official white iPhone 4 from Apple... running a previously unseen version of iOS! While it could also just be a clever set of Jailbreak tweaks, the video shows a new version of the multitasking fast app switching that replaces the dock icons in iOS 4 with miniature tiles of the actual apps, sort of like Exposé for iPhone.

Whether this is something destined for an interim iOS 4.4, our first hint at iOS 5, or some Jailbreak wizardry only Apple knows for sure. But it is interesting that it shows up on the anniversary of the Gizmodo iPhone 4 leak, isn't it?

UPDATE: Per comments, yes there are some old icons but also some Apple internal test icons. Weird. Second video from the same source that shows off, among other things, 64GB, a new rendering for Folders, and Facebook built into settings.

UPDATE 2: This might just be a prototype iPhone 4 running an early test version of iOS 4 which included Folder and Fast App Switching UI Apple later decided against implementing (going with what we see now in the release version of iOS 4.)

Check out the video after the break and let us know, real, fake, or really fake? And if real, what do you think?

For those who want a more Exposé-style app switcher for iPhone -- or any type of fast app switching on the still iOS 3.2 bound iPad -- Multifl0w for Jailbreak might be worth checking out.

Zoom out to reveal up to 9 apps tiled for easy access, re-arrange or remove them if you like, then tap to switch. $4.99 in Cydia.

Video after the break and if you try it out let us know how it works for you!

AppleInsider is adding to the multitasking rumors we've been hearing for a while now, saying iPhone 4.0 will finally extend the same benefits to 3rd party apps that Apple's own Mail, Phone, and iPod apps (among others) enjoy.

Using a key combination, such as the double Home click that now triggers Spotlight or Camera (or whatever you choose in Settings), the current app would zoom out and you'd get a grid view of all running apps, similar to Mac OS X's Exposé feature. Tap an app, it zooms in, and you're good to go. How many apps will be allowed to run at once, and whether or not multitasking will work on older, RAM-starved iPhone 2G and iPhone 3G devices is unknown. (iPhone 3GS has double their RAM, and we're hoping the 4th gen iPhone doubles that again for buttery smooth multitasking).

Whatever the implementation, Apple has a to make sure the new functionality is enough for power users but not too confusing for the mainstream. Apple's success to date has largely been based on their ease of use as much as their ecosystem so keeping that is key.

Also mentioned again is the Universal Inbox Steve Jobs "confirmed" previously, where you can see all new email messages in one view and not have to tap into and out of each account (if you have work, home, school, or any combination of multiple emails).

Lastly, they claim Apple will allow you to pin contacts to the Home Page for speed dialing, much as you could previously pin web page icons for speed browsing. Just tap the husband, wife, friend, or partner's picture and you're off an dialing.

We still have no idea when we'll see iPhone 4.0, but we're keeping our fingers crossed for a post-iPad beta launch and a typical summertime release. Right, Apple?

It seems like just the other day TiPb linked to a concept rendering of what Apple's Mac Exposé might look like for the iPhone, and now Steve Troughton-Smith, creator of Stacks for iPhone, has gone and brought it to Jailbreak.

It's not publicly available yet, not via Cydia much less via Apple. But do we want?
