Out of Memory Error

[Simpdapimp]

Pimp Down!
Lately i have been getting this Out of Memory exception Error ALOT. I am running IFONZ with not many customizations and no animations, and i run S2U and S2P from time to time, but anytime i have S2P open in the background and try to open any other app i get the out of memory error or the music starts to skip, DRIVING ME CRAZY. So i am asking of all of the different ROMs available which would be suggested that would have the largest amount of program memory available at startup, and would manage memory the best. Also if there is an App that will regulate memory on a consistent basis (when a program closes, reallocate that mem back to free prog. memory) then i think that would also be a possible solution to my problem. Anyone who can offer some help to a Pimp in Distress will be greatly appreciated.
