Icon ... you make a 57x57 png ... Put it somewhere in the resources ... Then change the plist to the icon name...
As for getting the app on your iPod Touch or iPhone you need to be a registered paid developer ... then apple gives good examples of how to test on your device in the program portal.
Since we're talking defaults, you don't even need to change the Info.plist entry to reference your Icon.png file. It defaults to this. So, just add an Icon.png file to your project and you're set.To elaborate, make a file called Icon.png, put it in your Resources group and change the plist entry to "Icon.png". It should show up in the simulator then.
By default it adds the glossy effect but there's another plist entry you can add to remove it.

That depends. Sometimes the resizing can loose some of the detail. As a general rule, an icon at 512x512, which is what the large application icon needs to be, is a great place to start. And usually scaling down to 57x57 is sufficient. But there will be occasions where this scaling down doesn't produce the right look. In that case, a good graphic designer will recognize that and adjust accordingly.Don't start with a 57x57 png, though. Start with a 400x400 (or even bigger) image and, when complete, resize it to 57x57.
I am new to Iphone SDK, and while the information is very useful on how to add the icon to a Iphone program, what program can I use to make the icon?
