JustJay passed along info on the AndroidPIT forums that Sony Ericsson's Xperia X10 finally has been rooted, which is the first step to get Android 2.1 running on the handset before SE releases the Android 2.1 update in Q3. On the XDA-Developer forums, thanks to Bin4ry Jerpelea, and biktor_gj, there are instructions for the rooting process.
AndroidandMe importantly mentions that with a root method for the Xperia X10, it shouldn't be very long before ROM developers get a fully functional version of Android 2.1 or possibly even FroYo working on the phone.
Engadget wrote that the post has "step-by-step instructions on how to locate your device ID, re-flash your phone, and then enable superuser abilities. It all looks particularly straightforward, as far as these things go," so take a look if you are interested and have an X10, of course.
Head on over to the root thread at XDA-Developers to get started.
