iOS 4.3 To Be Released Soon
Sources have mentioned that Apple has finished beta testing for iOS 4.3 and the code has been finalized. The 4.3 software is said to most likely include support for Wifi Hotspot for iPhones on the AT&T network. Currently only the Verizon iPhones support Wifi Hotspot. This is yet another way that will help keep the tallies even in the fight between Verizon and AT&T.
Boy Genius Report states we might see the iOS 4.3 to be released soon, even as soon as March 2nd at the upcoming Apple Event.
