What's the difference between the Surviving High School iPhone and the Surviving High School 2011?

I have really bad version on my phone that was free. (As in the graphics) Im going to assume you have the same one. Well on the iPhone you get better graphics and a new episode every Friday . There are many episodes and special packs for holidays and prom . You play word games and such . Theres also many characters : Hector , Amanda , Spud , Kat , Brendon , Dinah , Hector , Kay , Kel , Spike , Chip , Sam , Zoe , Zach , Porsha , Prissy , Paige , Taylor , Linda , Ryan , and Andy! And many more!
