Hey, do you still have an original AT&T Galaxy S II? Really? You should probably work on an upgrade. However, on the off chance you haven't already custom-ROM'd the ever-living-Cyanogen out of it, Samsung's rolling out an update for it, as we've heard at XDA, and had confirmed by Samsung's own support website. Note that this is the original AT&T Galaxy S II (model i777) we're talking about - not the Skyrocket.
The ATT GS2 was upgraded to Ice Cream Sandwich back in June, and that was largely considered to be the end of the update line for Samsung's previous-generation flagship on Ma Bell.
