Right on time, Sony Ericsson's begun rolling out the update to Android 2.1 Eclair (build number 2.0.A.0.504) for the Xperia X10, X10 Mini, and X10 Mini Pro. Judging by what we're seeing on Twitter and from what our tipster told us, it's only available in Scandinavia for now, so we can only hope that other regions will get to join in on the fun soon enough.

Our tipster also mentioned that Universal Androot does not work, although a bit of digging through the forums revealed that SuperOneClick does indeed root the phones, even after the update. On that note, where's our Froyo?

Thanks for the tip, Ola!

Update: Well that was fast - Eclair hasn't been ported over to X10s out of Scandinavia just yet, but you can trick your phone into thinking it's running Norwegian firmware so that you'll get the update today. Hurry up and head over here for instructions.
