According to Redmond Pie, iPhone OS 4.0 may be demoed on March 14, 2010. This would mark a major update to the iPhone/iPod Touch platform.
There is no real evidence that the date is true, especially considering that March 14 is a Sunday. However anything could happen!
iPhone 4.0 is highly anticipated to bring the ability to run multiple third party apps at the same time. Some of the rumored features that may be seen in 4.0 are the following:
Multi-touch gestures OS-wide. â€œA few new waysâ€ to run applications in the background â€” multitasking. Many graphical and UI changes to make navigating through the OS easier and more efficient. We havenâ€™t had this broken down, but we can only hope for improved notifications, a refreshed homescreen, etc. The update will supposedly be available for only the iPhone 3G and 3GS, but will â€œput them ahead in the smartphone market because it will make them more like full-fledged computersâ€ more than any other phone to date. Everyone is â€œreally excited.â€ The last piece of information is the most vague, but apparently there will be some brand new syncing ability for the contacts and calendar applications.
