What are some good iPhone games

I only have a few games on my iPhone like the common ones 'Angry birds, doodle jump, temple run' but I've heard there's hundreds! I have the APP store installed so I can download any of them. If anyone knows any good iPhone games and stuff- your answers will be appreciated- thanks!

Telemarketers call my Iphone at least 20 times a day. What should I do?

Just recently I started getting calls from numerous "unknown" callers on my Iphone. I answer and it is either someone trying to sell me something or no answer from their side. It is all day long that they call. It is a real nuisance to me because I have a business and since I'm always getting new clients, I don't always know their numbers, so most of the time I have to answer my phone in case it is a client. But lately its just a barrage of telemarketers when I answer. They call so much that I now recognize their number, but I have no way of blocking it other than paying my carrier (AT&T) $5.00 extra a month. What a rip off! Blocking numbers should be included in what I pay monthly for my service. Is there anything I can do to stop this?
