If you use the slider and go to settings then Data, the two options with check boxes cannot be read until you check the box. Not a huge deal because you can check the box then read what you did, but a glitch in the Matrix none the less.
I also did not see amaze gps. I thought it was cooked in, I installed the cab. No biggie, just didn't read it was taken out.
To get the speaker icon on the taskbar to match the blue signal and connection icons download the HTCVolumecontrol.dll that is in post #63 here
