At this point, you might as well flash CM10 for S2 so you are no longer infringing on Apple's patents. Lol.
I think the stock S2 Rom really does blow over time as it is not stable or solid over time the stock Samsung apps are so leaky and buggy too.
Root the phone, then download clockwork mod and select any of the popular roms to flash over the device.
Make sure you backup your settings or write down the configs.
