So is the Dev team changing their story? Is it a bug or not?
From what I read, it very clearly sounded as if it was not a bug at all; but rather a security measure that people were complaining about.
The reason I'm interested is that I've only experienced this 'bug' a single time - trying to download a HTC Sync application that I had very good reason to believe was responsible for corrupting my HTC Desire HD. But as I was downloading from www.htc.co.th - I stupidly tried to download it again. And bingo, the sole time I ever experience this 'bug' was the dozen attempts during which I tried to download HTC Sync. I don't believe it's a bug. I believe HTC Thailand have criminals administering their website.
I subsequently (like 30 min later) came to my idiot senses and downloaded HTC Sync from www.htc.com.au without incident.
