Contradicting earlier reports suggesting AT&T might enable Apple’s new Personal Hotspot feature on February 13th, which would require a release of iOS 4.3 on or before that date, MacStories reports that Apple is set to issue the new software a day later on Valentine’s Day. The Apple enthusiast blog cites a reliable source in stating that Apple will release iOS 4.3 at 10:00AM PST on February 14th. Other unconfirmed reports have suggested that the new OS build would be made available before February 10th, when Verizon Wireless’ iPhone 4 is set to launch. Among the new features expected to be introduced in iOS 4.3 are AirPlay support for third-party native apps and Web apps, a new option to configure the iPad’s slide switch as mute or rotation lock, and of course Apple’s Personal Hotspot function, which turns the iPhone into a portable wireless modem.
