I discovered something really handy today. A number of the icons that Apple uses in the iPhone UI are actually packaged as glyphs within the Apple Symbols font. Here’s how to get to them:

1. Open an application (works with most apps — I used TextEdit)
2. Go to Edit -> Special Characters
3. From the “View” dropdown select “Glyph”, and from the “Font” dropdown select “Apple Symbols”
4. Scroll all the way to the bottom of the screen and you should see what’s in the image above. Enjoy!

Note: You can also create a text field in Illustrator, select Apple Symbols as your font, and then go to Type > Glyphs to get the glyphs directly into a vector image format.
