Right now I am running Safestrap 3.05 and I have ICS .215 running for the main ROM. .215 seems to give me the best battery life and works very well for me. On the next slot I have been trying a couple different JB ROMS and found most of them to lack something that I need, like Bluetooth or camera. What I would really like to do is replace the JB build in the second slot with a stock .211 ICS ROM so I can get the official update to JB when it comes and still have my ICS .215 on the main ROM. Is that possible to do and if so where can I find the stock ICS .211 ROM?
