Who is your mobile provider i.e. orange, vodafone etc. If you have bought directly from Vodafone, I understand they do not update the firmware. This would mean you have to manually flash. Very easy to do and nothing to be too scared of, just have some guidance the first time.

If you bought from a company such as MPD (mobile phones direct) then you should have received the update by now. You can go into application catalogs and check for updates.

Let me know how you get on.
