Apple released an updated beta of iPhone OS 4 along with an SDK update to developers on Tuesday. The updates for the next version of the iPhone operating system will be available for iPhone and iPod touch users this summer, and some time in the fall for iPad owners.
Apple CEO Steve Jobs introduced iPhone OS 4 on April 8th at a special media event in Cupertino. The new version of the iPhone operating system will include several welcome features such as multi-tasking support for third-party apps, folders for organizing apps, a unified inbox in Mail, and support for Bluetooth keyboards.
First generation iPhone owners, however, won’t be able to upgrade to the new operating system when it ships, and iPhone 3G won’t be able to take advantage of the multi-tasking features.
The update is available for registered iPhone developers at Apple’s Developer Web site.
