If you own a Sony Xperia device, there’s a good chance you can run the software from many other Xperia devices. In fact, we’ve written about it a number of times. There is now a way for Xperia X10 owners to run pretty much the entire interface from the Sony Xperia S.
Released by XDA Senior Member Emperor.dk, the package includes a number of elements to help your X10 feel like a Xperia S. To use, simply download the zip and flash it in a custom recovery. If you want to uninstall, you’ll have to restore a Nandroid backup—which means you should probably make a Nandroid backup.
To make the experience more complete, Emperor.dk has also included links to other applications to supplement what comes in the mod. These include the Xperia S launcher, the Xperia S lock screen, and the Xperia S CM7 theme for theme chooser. Additionally, there are links to the Xperia S fonts, more apps, and Timescape. If you enjoy the Xperia S look and feel but don’t (or can’t) dish out the money for an upgrade, then this is a perfect way to get the experience without buying the phone.
