Another really pointless reply from them.. in the initial contact I mentioned the camera being misaligned so that's what the first part is referring to. Here's the latest reply and below it is how I have just responded.
Since receiving your e-mail i have looked for any more known cases and was unsuccessful if you are concerned that this may cause issues i recommend that you take the device back to the retailer.
Regarding the LED,
We do not give developer support so i cannot help you with this.

Response to it from me..
With regards to the LED notifications, I'm not asking for developer support or any support in fact. I'm simply trying to find out if HTC have changed the method for using them with the Desire HD. You said that programs are coded for specific phones and I'm sorry but that's not true. They are made for SDK versions, most going as far back as Android 1.6 for widest compatibility, so any changes in the programs affecting the LED notifications would show in ALL versions, not just the version shipping with the Desire HD.
This again points to either HTC changing something with the Desire HD or a programming bug with the Sense UI in some way. I realise this isn't an easy issue to look into but it is a very important one and while I appreciate you're trying your best, I will not let this issue drop until I get a more satisfactory answer.
To me this is a very big deal because if you leave the phone for a few minutes and aren't close enough to hear an audio notification
is what I rely on. Missing notifications like this I might expect from a custom ROM but I haven't touched the phone in any way like that. I didn't see your reply in time to mention the GMail issue and I only have my experience to go on which is Twitter updates not always firing. You should raise a ticked too, the more we get raising the issue the better the chance they'll look into it.
