It looks increasingly likely that Apple will launch the iPad 2 on the 13th of February with the iOS 4.3 coming one day later, which would correspond to the end of the day at the Mobile World Congress in Barcelona.
Macstories quotes a reliable source to back the above statement adding that iOS 4.3 will be live by 1000 PST; iOS will improve support for AirPlay, clean up the existing code and introduce iTunes app subscriptions that will support The Daily and other third party APIs.
This obviously reminds us of what MacNotes, a German website, published last week; an anonymous iPad accessories manufacturer had said that Apple would be planning a small event to launch the iPad 2 and the iOS 4.3 at the same time.
Apple might time the release to occur on the 13th of February which is the Sunday before MWC. The iPad 2 is unlikely to go on sale before the end of April 2011 with the tablet hitting other territories in the second half of the year.
