I've got a iPhone, now what?

So you've finally jumped on the smartphone bandwagon and got yourself an iPhone.  Besides Angry Birds, what other things should you get?  Here's a few of my favorites:

• Invest in a nice case to protect your phone.  Screen protectors are not really necessary as long as you're careful of what you keep in the same pocket w/your phone.
• Get a car charge kit so you can keep your iPhone topped off when you're driving.  Some kits will even plug into your AUX port in case your car doesn't support A2DP.
• Google Sync will keep your emails, calendar and contacts backed up and stored in the cloud.
• Evernote replaces the Notes application and will act as a one stop shop for all your memories.  You can even store Word and Excel files now for free.
• Slacker Radio and Pandora offer thousands of radio stations all at your finger prints.
• Find My iPhone will see where your iPhone is via GPS, ring the phone, and if you have to, wipe the data.
• Skype is the best way to video conference with other mobile users as well as desktops.
• ESPN ScoreCenter keeps you up to date with the world of sports.
• With Shop Savvy, you can scan bar codes and compare its prices.
• HeyTell is push to talk for your iPhone.
• GroupMe will create a SMS mailing list so you can send one message to multiple people.
• Read reviews of restaurants, bars and other cool hangout spots with Yelp based on where you are or where you'll be.
• Track your data usage with My Verizon Mobile so you don't go over your data plan.

This is by no means the definitive list of things to get your iPhone.  As you start using it, you'll discover a lot more on your own.
