Default [Q][SGH-i847]¿Dual Boot for daily testing?

Hi!

As far I know there are a lot of roms for this little device. The roms in current development lack camera support or have some other issues. I could live without the camera 99% of the time but i just can't make a back up and flash everytime i need to take a photo or buy another cellphone. I wonder if there is a way to use some other ROM with dual boot in this device. I've found an app and instructions for other devices but this phone it's not supported

PTA:I'm a noob in android development. But i can be a great guinea pig.

Thanks in advance.
