For those on Orange branded phones, the Sense 3.0/OS 2.3.5 update is now being rolled out OTA. It's about 231MB in size. Once downloaded, it takes about 15 minutes to install and boot up.
On completion the new Orange software number is 2.13.61.3 and the Baseband/radio is 20.4801.30.0822U_3822.10.08.04_M, which is the latest stock radio version.
As Orange, T-Mobile and Virgin are connected by the same company, my guess is that it's being rolled out to all three at the same time, although obviously not the same software version. (Recent reports said that a Virgin/T-Mobile update had been released earlier this week.)

Edit: The T-Mobile OTA (UK) is being rolled out, too. (See here.)
