Afraid that if you bought the phone through the operator and they brand the rom (I imagine a Chinese one would be branded), then you'll have to wait a couple of weeks as Sony release the update to them first so they can check their branding still works ok with the changes and then it gets released to us.
The guys who've already got it are guys who bought it up front.
