Apple has seeded the golden build of iOS 4.3 to its developers. iOS 4.3 is scheduled to be available for public on March 11, and includes new features such as personal hotspot and iTunes home sharing.
iOS 4.3 however will not be available for older iOS devices. iOS 4.3 will be available for iPad, iPad 2, iPhone 4, iPhone 3GS and third- and fourth-generation iPod touch. And it will not be available on Verizon CDMA iPhone which is running iOS 4.2.6. There is no mention if iOS 4.3 will be build for CDMA iPhone but we expect Apple to release iOS 4.3 features in future iOS update for CDMA iPhone.
