iPod touch (SOLVED) Putting Mail on the dock

[thesdx]

I've found out how to re-arrange icons, but I can't figure out how to put Mail on the dock. What key is it? (Ex. com.apple.????) If this helps, here's my N45AP.plist file:

<?xml version="1.0" encoding="UTF-8"?>

</dict>
</plist>

EDIT: I solved it. I just had to change "com.apple.MobileMail" to "com.apple.mobilemail".
