It's easy, you just need Odin then put the phone into Download mode. There's no way to break a Galaxy S2.
Don't be scared! It's pretty straightforward, and once you do it, you'll feel more at ease with doing it again!
(sounds like a lot of other things.....!!)
Hmm, will have to see if Mrs AT's phone will find the upgrade this weekend as she's on O2.
Just updating my Sensation on Vodafone now.
Is it an over-the-air update?
I'll have to fiddle with the Missus' S2 later (fnarr).
... and now I have even more impetus to replace my Orange SF... it's upgrade time on saturday.
just downloading on my S2 now.
Just rooted and changed mine to ICS. Dam that was quick and easy. :)
Found out yesterday I can't root my Sensation yet as the H-Boot is too high a version. :(
I upgraded to ICS via kies over the weekend. IT has frozen a couple of times on my handset. don't know if that was the app i was using or what.
Got the official ICS update on my S2 last night on Orange. Working rather nicely now after I'd done a factory reset as it was a bit messed up before that.
Was sat on the o2 ICS upgrade for a couple of weeks now, and have recently installed the F1 GalaxyNexus ROM, very simple, very fast, Straight ICS4 without any touchwiz or any extra software. Perfect for what I wanted and looks far better IMO
