Hi there! I have just bought a new Android phone (2.0 Android software) and it's my first one. I'm SOO excited, but I'm not quite sure what are some good apps! It's the Xperia X10 Mini, and doesn't have much space for apps. I'm interested in productivity, arcade and reality games and any games that are interesting. I can download apps that cost money, but no more than $5.00. Please help!
