I just got off the phone with HTC Support. The guy I spoke to was very helpful & knowledgeable. I asked him whether the HTC Trophy will be getting the 7.8 update. His response was “Ultimately, yes.” He said he could not give me a straight answer on future updates for company policy purposes. The answer was the same for all HTC WP7.8 devices besides the HD7. This means that devices like the Trophy, Mozart, Arrive, Radar, Etc… will get the update.
He also said that HTC has little to no control over 7.8 at this point. At this stage, it’s strictly up to Microsoft. HTC was able to approve all phones except the HD7 for the update. When the update is released, all HTC will do is announce that it’s released. Microsoft will release it to Zune and HTC WP7.5 users can update at their own will.
The reason the HD7 was not approved for the 7.8 update was because of one hardware deficiency: a shutter button. The lack of that one hardware requirement makes the HD7 ineligible for the update.
This is what the customer service representative was able to share with me. It seems like this ultimately does not fall on the backs of HTC, but rather Microsoft.
