Vietnamese website Tinhte, which is well known for leaks has released a video of a 64 GB White iPhone 4 running some test of unreleased version iOS 4. The video reveals multitasking and search spotlight features. the news comes from the guys at Engadget:
We’re looking at a prototype unit and taking us on a tour around its body. A visit to the Settings menu shows a 64GB storage capacity, while app folder creation is also handled a little differently from iOS 4. The presence of the Touch Fighter app on this phone, which Apple built to show off the capabilities of earlier versions of the handset, and other internal-looking software seems to point to this indeed being some form of iOS beta build. Of course, it might not be iOS 5 at all, but simply a never-released version of iOS 4. All we know for sure is that the video’s after the break.
All indications are that this is indeed an early, unreleased version of iOS 4. Interesting, but probably not something to get your hopes up about.
