upgrade from s 2 to s 3

I personally haven't but in my opinion, I wouldn't upgrade. The s4 is supposed to be released in quarter 1 of this year. I think your better off waiting for that :)
 
More like beginning quarter two, but yeah if you haven't upgraded yet and have no problems, wait to see what is coming up at the end of February and the s4 announcement

But to actually answer your question, it is a pretty big improvement in some areas but not huge once jellybean and the newest UI gets on there.

Has anyone upgraded from the s2 to the s3? If so, did you think it was worth while to you?
I upgraded from the S2 to the S3 in mid October last. After doing so, I wished I hadn't, except that I liked the physical home button?which was the main reason I upgraded?having had iPhones for 3+ years. But the apps & widgets were way better on my (AT&T) GSII Skyrocket w/ ICS 4.0.4. Way better.

If you wish, I can get more specific tomorrow; no time now. Don't know what carrier you're with, or if you have a Skyrocket, so YMMV.
