Ok, I geeked out, and this is probably more information than you need. But it completely answers the question. Sorry. ☺

Locally, I'm at this commit:

$ git show
commit d6cd1e2bd19e03a81132a23b2025920577f84e37
Author: jnthn <jnthn@jnthn.net>
Date:   Sun Apr 15 16:35:03 2012 +0200

When I added FIRST/NEXT/LAST, it was idiomatic but not quite so fast. This makes it faster. Another little bit of masak++'s program.

How the get the 512x512 icon for an app.

Look for this app on the itunes.apple.com website (Google is your friend)

For example, this excellent app.

http://itunes.apple.com/au/app/bancomap/id309009025?mt=8

Look for the URL of the icon in the page (it's a 175x175 picture).
I use Safari, so right click on the icon and choose "Inspect Element"

baz

float screenResolution() {
	struct utsname systemInfo;
	uname(&systemInfo);
	char *name = systemInfo.machine;

	float ppi;
	if ((strstr(name, "iPod") != NULL) && (strstr(name, "iPod4") == NULL)) {
		// older ipod touches
		ppi = 163;
	} else if ((strstr(name, "iPhone") != NULL) && (strstr(name, "iPhone3") == NULL)) {
