Samsung has a dodgy history when it comes to software updates on their smartphones. Any one remember the dead batch of Focus Windows Phones after the NoDo update? The Gingerbread fiasco on Galaxy S? Sadly the company isn't doing itself any favors by backing out of the 10th March deadline for ICS update on Galaxy S II, which the company made official it self a few days back.
According to Samsung, they're 'recalling' the update. What that means is anybody's guess. Thankfully they aren't giving any more dates so you have nothing to look forward too. Just keep checking Samsung's Twitter account for any update on the update.
