Regarding icon sizes for mobile


[SIZE=15px]I noticed the apple guidelines mentions that app icons are 120x120 but when I go to something like photoshop or fireworks to see how that looks like, it looks much bigger than that. Anyone know why?[/SIZE]


Where are you viewing the icons?


What I do is screenshot on the phone and then email myself that image. I then open up that image in Adobe Fireworks and it is bigger. I know resolution has to do with it but I am trying to find out how as a designer we should be choosing the sizes of icons for mobile.
