Which iPhone apps do you like?

So, I finally joined the 21st century and got an iPhone. Until now, I had been rocking an old-school flip phone, which most people assumed was a toy for Toby. But then I lost the battery, and when I tried to replace it, Verizon told me they didn't make it anymore. I was like, OK, I get it.

Now I'm excited to have a shiny new iPhone. My only question is: What apps are awesome? I know nothing about iPhone apps--except Hipstamatic--so I'd love to hear your recommendations! Which apps do you use? I'm clueless!

P.S. Me with my old phone:

Five best board games

Do you like playing board games? I love having board games around the apartment for when people stop by or friends stay the night, since they instantly make an evening fun and funny. Here are my five current favorites...

Jenga gets everyone's heart racing. (Alex and I played it a lot when I was pregnant.)
Scattergories is perfect for quick-thinking wordsmiths.
Taboo always makes people laugh (especially with the buzzer).
Have you played with an Ouija board since you were 16? Turn off the lights, gather around and ask it spooky questions. (Bonus: The updated version glows in the dark.)
Mancala is the perfect game to play with a glass of wine in hand, and it's fun for both kids and adults (it gets harder as you get smarter!).

What games would you recommend?
