Games I like are Angry Birds Rio, Angry Birds Space, Super Ludo, Temple Run, Fruit Ninja, Bejeweled, Jetpack Joyride, Bad Hotel, Lili, and Bingo Blitz.

My other fav is Blux Camera… It's a brand new app that I've really been loving. It automatically tells you the weather, and senses the environment (lighting and such), then tells you which settings to use. There're really cool retro filters that you can use, plus you can control the saturation, sharpness, temperature, etc. It also has a lot of different modes, like portrait, landscape, food, etc. The cool thing, though, is that you can apply all the effects before you snap the photo… So you know exactly what the photo is going to look like before you take it. It's also really easy to upload photos onto Facebook, Twitter, etc. It's also nice, as it improves the resolution of the iPhone camera, making the pics clearer. So if you ever want to print them or make them into posters, they come out much better.

I also like Photography 101, which teaches you how to take photos. If you want to learn a language, there are also flashcards and dictionaries…
