There’s a new ROM available for Sony Ericsson XPERIA X1 handsets, via the official X1 update system. Known as R3A, this update brings better touch response, a brighter keypad, better texting, a faster media panel and overall better performance and signal.
In order to get the new ROM, you’ll have to use the update service, located here. All you have to do is download the installation package to a temporary folder on your PC, run it and follow the on-screen instructions. This service is compatible with Intel Pentium 4, 2.0 GHz or higher/AMD Athlon machines, with at least 500 MB of free HDD space and 512 MB RAM.
You’ll also need an available USB 2.0 port, Windows XP with SP2 or later and preferably a broadband Internet connection.
