was searching and heard on I think xda that there is a forum for cricket user with ppc's on howardforums. Thats where I found this. But its pretty much like I suspected.
I read it a little to see if it was something that would help you and it looked like it was on the right path. Theres 12 pages so it should get you your answers.
Good luck and its not nice to get mad at people trying to help you out. Nobody is gonna hold your hand in doing this. You just gotta read. Like myself and many others have done. If you dont understand a work or abreviation just google it.
Heres a few other threads that might interest you also.
