Here's a funny little anecdote that will affect about 0.2% of you: the HTC Mazaa, basically a limited edition developer device, doesn't seem to recognize that it's an HTC phone. Poor thing.
Reader of the site Achia S. won an HTC Mazaa from Microsoft's WPAppItUp contest. Wanting to install the HTC Flashlight app, they get a notice stating that this app only runs on HTC phones and therefore, you can't have it. Obviously the problem here is that HTC along with this build of the OS aren't recognized by HTC's validating process--something they could probably fix, but are in no rush to address. In fairness, HTC was kind enough to respond to Achia's inquiry on the matter:
"I understand the importance of having an HTC 7 Trophy that functions as it was intended. Unfortunately, with developer devices, we cannot ensure that the ROM on it will function as the released model. I recommend contacting Microsoft to see if they can push the Release build to your device and have it running the appropriate software. I do apologize for any inconvenience."
It's interesting that HTC tech support conflates the 7 Trophy with the Mazaa--they are similar devices but different internals and it's not clear that a finalized ROM will fix the matter either. It sounds more or less like HTC needs to add the Mazaa to their recognized database, but whaddya we know? Thanks, Achia S., for the heads up!
