I emailed HTC to ask when this would be available and got this today:
Dear Paul, Thank you for your enquiry about HTC Desire, We are working closely with Google and our other partners to ensure we have the earliest access to everything we need to provide a complete and solid HTC Sense experience on Froyo. We expect to release all updates in the second half of this year but can't be more specific yet. Best regards
Sounds like its a long way off and no idea when it will be finished!!! I wonder if the HTC Project Managers just tell their bosses "it'll be finished in the next 6 months I guess"?
Not impressed...where are the rooting guides?
