Turns out Twitter is the best possible way to get updates on mobile firmware upgrades. Tipster Ben Hersey pinged Vodafone's Twitter account to find ut when he might get Gingerbread on his Desire HD. And he got an answer.
We've just finished testing for 2.3 and will have more news soon. ^ZO
While that doesn't offer anything new in terms of release date for the update, it's still good to know that the Telco is past the testing phase, which is generally the biggest delay in rolling out OTA updates.
[Twitter - Thanks Ben!]
