It would appear that the update is dependant upon your CDA number.
I key my CDA number in and get the following :-

For CDA162004/29, the latest organiser version is R3A06. Now you need to
compare this version number with the one in your phone.

Just curious, what country you in? What language is your phone? Where was
your phone sourced from. It is interesting that updates are dependant on
CDA number (whatever CDA stands for)

It would be interesting to know what the release notes are.
