To make a long story short, I had to reinstall the OS on my S2 with what I thought was the stock version. When I connect to Kies I get a message saying that the firmware version can't be upgraded using Kies. Does this mean that when the Jellybean update becomes available (next month supposedly) I won't be able to update? From what I understand it has to be done through Kies, because AT&T won't be doing an OTA update.
