modern combat 2

OK, I have seen many hackers online and I'm pissed. I have the speed hack thanks to Mr big stuff, and I use gamecih to change my rank and stuff, but gamecih always return things to default when closed. I am now extremely jealous of iPhone cause I also realized that u can do a bunch of other cool stuff with itouch and iPhone and that ios is smoother. So I anyone pleaz have a way to get gamecih to keepp things permanently or if there's another way to hack it like godmode or change avalanche map or maybe even fireblood, I would be extremely greatful.
Also, pleaz don't say random stuff such as suggestions I should like, hack gamecih or something:'( and make sure the hack u r posting works 100% .
