Rumors say no but its basically a waiting game right now on a definite answer. If you're into rooting there's a custom rom based on 2.2 over on the xda developers forum but its still in beta mode. Main: Xperia X10 2.2 - Unofficial
Thanks for all the welcomes
I've only just heard about rooting my phone on here. Not really sure how I go about doing it though. I understand it's similar to jailbreaking an iphone but thats all I know. If I was to root my phone would I be able to get the OS updates? Does anyone know how to root an X10?
