Thanks. It was a thought but I look after a few S2s and I'd like a quick way of doing it (ie just click on Update) rather than going the rooting direction, which may cause you to get deprived of Telecom support.
Are you meaning 4.1 aka jellybean or 4.0 aka ice cream sandwich?
Because ics came out about mid-year as a telecom update. I downloaded the update for Dad's S2, and I remember there being a long thread on geekzone about when the update would finally arrive, and it ended with the update arriving.
I've gone into Kies Air and connected my S2 and the PC, and I can't see anything system-related (apart from a file explorer) on the Kies screen on the PC. It seems to be just messages, contacts, etc etc. All info gratefully received.
If you can PM some details, please include a screenshot of the Settings > About device screen too if you could. Or if you want PM me an email address and we can move it to there, see what I can do to help.
