I also asked HTC about Froyo update for the Legend. And see below what a ridiculous answer I got:
Thank you for contacting HTC. Thanks for contacting us about Froyo. We thank you for your interest in our future products, but we cannot officially comment on our future product roadmap. If you have any other inquiries, don’t hesitate to contact us again. Please note that you can contact us via support line. For further details, please go to HTC hotline, Thank you so much for using HTC products. Respect & Regards, HTC Team
I think the representative who answered is pretty uninformed and technically illiterate.
After all I haven't been asking about "future products" but for firmware update of a current device... So still no 100% confirmation for Froyo update for the beloved Legend.
