There has been quite a bit of speculation on the date that Apple would make the iPad 2 official, now it seems that a possible date is the 9th of February 2011.
The original iPad was announced on the 27th of January last year, and the date that appears on the calendar on the iPad homescreen in the official Apple press material is the 27th of January.
Now a new calendar icon has been found in the latest beta version of iOS 4.3, and the date shown on this icon is the 9th of February, which could point to the 9th of February 2011 as the date that Apple makes the iPad 2 official.
The 9th of February may make sense for Apple, as it is before MWC 2011, where there will be a lot of new tablets and smartphone announced, so announcing the iPad 2 before MWC could be a good move for Apple.
Apple has now announced their third iPad, have a look at our handy guide on the iPad 3 vs iPad 2 to see the difference between the two versions.
