The Sony Xperia S is one of Sony’s first dual-core devices promising stability and lightning-fast processing speeds. But, don’t you know that the custom modding community at XDA Developers is also porting the Sony Xperia S firmware to run on older Sony Ericsson devices such as the Sony Ericsson Xperia Arc?

This feat has been made possible, thanks to XDA Developers member zohaib0001, who managed to port the Sony Xperia S ROM to the Xperia Arc S. The Sony Xperia S firmware perfectly runs well on single-core devices and considering the Xperia Arc is a Sony-branded device, there should be no problems when it comes to stability once installed.

However, there are a few applications that are still based on the Xperia Arc firmware, but the developer has promised that those will soon be replaced with the official ones found on the Sony Xperia S.

Excited to get the Xperia S firmware running on your Xperia Arc? Continue reading and find out how you can install the Xperia S firmware on your Xperia Arc.
