king17, firstly, im not a dog. I dunno, maybe your pals are, but I am not. And if it is true, then your phone is simply a shit, get rid of it and get 6120c. Bcause 6120c is kinda old now and it is cheap, that wil lsolve most of your problems.
Also, your mentioned prince of persia HD or Ferarri Gt HD games might not work, because they are HD games, and 6120c (6124) are slow phones, so, even if you succeed to run them, they will most probably lag way too much...
