Barbies & iphones

I don't know who is more excited. My daughter or myself. See, today she got her very first Barbie doll and I got an iPhone. I do not spend money on myself. There is always something else I think I could spend the money on for the kids. When my husband mentioned getting an iPhone I told him we should wait......well I don't know what I was thinking because Ilove this phone! I can't even see straight from browsing apps! I am completely hooked on angry birds although my daughter is better than me! If you have an iPhone what is your favorite app?
