comes up with 2189 on my nused 40d!!!!!! and i took a pic and it then said 2190. i hate to get excited since last time i tried one of these i was wrong, but so far it goes up one every time i take a picture.

can any of you with a new camera test it and compare to what you know you've taken?

his site says it should work with all digic 3 and 4 cameras. iunno.

p.s. it's virus free as scanned by AVG
