[HD2 Windows Mobile 6.5 ROM Development] l3v5y:
- calender wont go past 1.nov.2009 in week-view (monday set as first day of the week)

That's fixed in 1.48

- g-sensor not working in titanium (no titanium landscape switch)

Why should it? You can add it manually, and HTC probably would remove Titanium if they could.

- notification LED doesn`t work

Mine does... What's the issue with yours?

- connection to the internet without a timeout/break (gprs-disconnect timeframe should be larger)

That's just a tweak, not a bug as such.

- voice command does not work with a bluetooth headset

There is no Voice Command.

- volume of a stereo-bluetooth headset cannot be controlled. The device volume has no influence on the headset.

That's probably the Widcomm bluetooth stack, but why can't your headset just be set at a lower volume?

- storage card is called "storage card" instead of "speicherkarte" in the german rom (might cause problems installing apps)

- view music by recently added

Does anything do that at all?

- volume cant be adjusted during a call when in handfree mode (speaker on the back)

Mine can...

- overstearing speaker sound (back-speaker)

Not quite sure what you mean by that.

- purple center in pictures taken with the hd2-camera (htc is working on a hotfix)

That is actually a bug, and I get that...

- sporadic volume control failure in Music-tab/streaming-player

Never had that, volume control works all the time.

- audio-booster disabling itself after playing a song

Have you turned on repeat, or got it playing more than one song?

- HTC Messaging takes all SMS's and stops them from being published on the "notification queue" that other programs can listen to

What else needs the SMS? I'm fairly sure that the SMS events are still set and can still be accessed.

- Sms not being sent/delivered (can't confirm that, works for me)

Works for me too.

- 3g-button missing in comm-manager

It's not missing, HTC just decided not to have it active.

- geotag (camera) is implemented but deactivated

That's what footprints is for...

- taskmanager quickmenu missing

It's an HTC add on when it's there, why can't they choose not to have it? I personally find it useful, but it's hardly the end of the world...

- taskmanager icon missing in list (to assign quick button in sense-homepage)

That's because it's hidden away, probably in the expectation that you don't need to close programs. Have you ever had an out of memory warning?

- navigation panel link missing in startmenu

That's because it's for use with the HTC extra hardware. It's not missing, it's just not of much use without the hardware.

- taskbar icons (phcanoverbmp.dll etc.) from wm6.1. Should be the rounded edges/G/H/3G from wm6.5.

Those are HTCs icons anyway, and they may be the same as the older ones from older builds, but what's wrong with them?

- facebook contact pictures and birthday should be saved in contact details (you loose the friends fb-pics and birthdays when disabling fb-sync-feature)

I don't see why this is an issue... If you want the stuff from face book, why disable it?!?

- opera zoom-slider and more tabs

Why bother with the zoom slider when there's multitouch, and why do you need more tabs as it'll inevitably slow down the device and so you'll complain about that instead.

Note, I'm not doing this to criticise, but to attempt to explain why these aren't really bugs, but things you don't like. They are all perfectly explainable (apart from a few exceptions).
