ok first: +1 means that they agree and are looking for the same thing...
As for a stable Rom that doesnt freeze... Good luck man. lol. No matter how stable the rom may be, ANY PPC phone is gonna freeze from time to time. The processors are just not big enough to handle all the stuff we want them to do. If you want to avoid freeze-ups and crashes as much as possible then the best bet is gonna be using a very basic no frills 6.1 rom. But in my opinion thats not really the point of flashing.
