203 is the vanilla Handsets (No Branding) 205 is Vodafone direct handsets. If you got it from MPD or CFW even though the contract is Vodafone and its exactly the same if not better than Vodafone Direct, their handsets are 203 (Vanilla)

Only handsets DIRECT from vodafone have 205 and are "Branded"

It seriously sucks if theyve locked out all the features that make the phone what it is.

Think you need a reflash, but I'm pretty sure this will void your warranty with Vodafone direct, as it is not the "series" of firmwares "they" designed to be run on the handset.

Sucks if thats the case, I know thats the policy they had towards unbranding the Voda N97 with "Vanilla" firmware.

Hope this helps.
