Your choice seems OK, but see http://support.apple.com/kb/ht3011 just to be sure.

By the way, I bought this and it's working fine.

"1333MHz DDR3 Non-ECC CL9 SO-DIMM" is the type of memory used for all of the July 2010 iMacs.

See: http://eshop.macsales.com/shop/memory/iMac/2010/DDR3_21.5_27

It comes in 2 GB and 4 GB capacities.
