Apologies for raising everyone's hopes about the possibility of iOS 4.3 being released today, all for absolutely nothing to happen at 10 AM Pacific Time, but apparently it’s actually supposed to be released tomorrow, according to Jim Dalrymple’s The Loop column. Dalrymple says that despite Steve Jobs announcing at the iPad 2 launch that iOS 4.3 will be released on March 11, the same day as iPad 2, he believes that it will indeed be released early - tomorrow, Wednesday 9, in fact. MacRumors also has more hints about a possible early release tomorrow, with the log of a chat session between a MacRumors reader and an Apple Store Chat representative, who said that iOS 4.3 would indeed be released on Wednesday. On the other hand though, MacRumors says that they have spoken to another Apple rep who says that iOS 4.3 will be released on Friday as scheduled! Worth having a quick look at iTune tomorrow at 10 AM Pacific Time anyway!
