First of all the reason you are not seeing an update through HAM is because your firmware version hasn't been updated yet.
You are probably using a 205 firmware variant which is for UK vodafone handsets.
You have 2 choices, either reflash to the Global/UK image or wait for vodafone to push the update too you (personally I'd go for the former, rather than the latter).
