As the Samsung Galaxy S2 has reached its service life, which typically for most smartphones is 2 years, it is not expected to receive a OS update from Samsung or the carrier (AT&T in this case). However, there are a number of custom ROM's that are KitKat to choose from.
It does not appear to be available, if it was even available at all. With newer phones (even from Samsung alone) flooding the market, it doesn't make sense to still offer a case for the Skyrocket, which is going on nearly 2 years old from it's November 2011 debut.
The Samsung galaxy Europa is awful. Buy the samsung galaxy apollo!
