Although I was told via Vodafone that the firmware update would be posted on the site, it is not as far as I can see, but just for funsies, i decided to check via my X10, And yass! Its telling me there is an update available.
Although it does not mention 2.1 it just says I have to plug my phone into the computer to update.
I assume its 2.1 and not Vodafone pulling my arm here, Ill get back to you once I see what it is, booting up the PC now
