Slim GSM pickings around here

[Cab]

I have read and read and read around this forum. I have tried many things which seem to be for CDMA phones that work on our GSM versions.
There is a also HUGE post on getting FM radio working for the CDMA that was closed today. It was mentioned many times that we can get the FM radio working on our GSM models. Well I have done searches and you have to have a minimum of 3 charactors to search. FM wont work and Radio brings up a lot of ROM's so I am asking here and hope I dont get flamed to bad for it? Got a link to a how to do this? I prefer to use a cab and not a custom ROM (still scared Ill brick it)
