Tech Ticker

Apple has upped its biggest OS release for its iPhone and iPod touch users. The iOS 4 is available on iTunes for all iPhone and iPod touch users except for the first-gen model users. The update is free and can be downloaded after clicking on to Check for Updates.

There are over 100 new features but few notable ones are the multitasking support, folders, iBooks, iAds and more. However, all new features won’t be available to iPhone 3G and second-gen iPod touch users, apparently due to the device’s low availability of RAM.
