Apple Seeds iOS 4.3 Golden Master to Developers
Apple today seeded the golden master version of iOS 4.3 to developers, paving the way for a public release of the update on March 11th.
The update is available in versions for the iPad, iPhone 4, iPhone 3GS, and third- and fourth-generation iPod touch, while the iPad 2 will of course also ship with iOS 4.3 installed. The build number is 8F190.
BGR last week claimed that iOS 4.3 had reached golden master status, correctly pinpointing the build number of today's release.
Update: Apple has also released a new golden master version of Xcode 4 known as "Xcode 4 GM seed 2" to support iOS 4.3.
