In this shot with S3 IS, f5.0, 1/60, focal length 12.1, AWB, Aperture Priority, how come I can't get sharp edges on the can?
Can anyone advise?

Agree with you...Robbo73 said:Just realised the top of the can is relatively sharp all the way round so d.o.f. unlikely to be the cause. May well be the large contrast difference causing fringing (often seen when taking pic of trees & buildings with very bright skys).

Robbo73 said:The more I look at this, the more convinced I am that it is a function of contrast and maybe flash-related shadow - the background is also still a bit too light (light bounce back?). I also note that the position of the can isn't helping... the bottom left of the can at the side is one of the white Coke "ribbons" which gives an illusion of softness as well. As mentioned, the top of the can seems fine so lets assume it's CA or PF.
A few things you could do (in order...if you have the time/can be bothered)
Post a 100% crop of the middle of the RH edge of the can (to look for PF/CA which lead us to believe it's a lighting/contrast thing) - maybe for each of the pics above to see differences?
Repeat with black background & play with lighting types (dir flash, daylight...)/angles (1 side, above, front) as mentioned by cyber m0nkey.
Repeat the same shot with a different lens (some lenses suffer from CA more than others)
Repeat the same shot with same lens, different body (PF can be as a result of sensor issues - not always linked with CA)
