Sony Xperia S has supported dual boot with Boot Manager. Sony Xperia S has supported Android dual boot with Boot Manager, Senior member of xda letama has released a dual boot with Boot manager developer.Aplikasi version is still under development at the Xperia S that still need to get the development of the other party developers.

This is for devs and advanced users only, you would have to fiddle a lot to get the second build to run, you need an arm toolchain to embed both kernels and you have to modify its cpio.

I’m working on tools to flash kernels directly on device, but they’re not ready yet. And ideally, CWM would need to be extended to support two environments. Don’t expect quick progress, I don’t have much free time to work on this.

Here are some details on how it works:
- Trimmed down a stock kernel to remove some fat and add a driver to set a specific memory location.
- Embed a small assembly loader with this kernel and its cpio plus the other 2.
- The tiny kernel is loaded first, it displays the menu and eventually starts cwm. The menu will set the memory location with the kernel choice, then reboot.
- At next reboot, the assembly loader will detect the kernel choice and start the appropriate kernel.

For those developers who want to develop applications that can easily join the XDA Developers
