The Skype app for iPhone was officially unleashed this morning, and just in case you aren't already convinced you should download it, here are ten bonafide reasons why it will completely rock your world:

1) It's free to download.
2) It enables free international calling.
3) It works on iPod Touch (with speaker/microphone add-on).
4) It means you can save up those priceless AT&T minutes.
5) It syncs up with your existing phonebook. 

Five more reasons after the jump:

6) Yet another avatar you can personalize and add to your slightly schizophrenic virtual personality lineup.
7) The iPhone Skype launch totally beat the Slackberry, ahem Blackberry, launch.
8) Three words: international prank calls. Hello, Australia? Is it true that your toilets flush backwards?
9) Make free calls whenever you have WiFi access.
10) Everyone else is doing it, right?
