UPDATE 12/31/09
I went to Sprint store to pick up my replacement phone, Sprint technical support told me that my phone's internal antenna could be causing the problems, etc so that's why they sent me to a Sprint Store.
I walked in to the Store and they went ahead and activated the replacement phone, I tried to watch a YouTube video and I kept getting the Cannot Play This Video message. I went back to Home screen and pressed Menu>Settings>About Phone> info
x.x.xxx..x.2 (phone has been updated)
I just asked them to reactivate my phone since I had paid regular retail price and it makes no sense for me to change a phone for another phone that is having the same issues. I also asked them if I could get a phone that hasn't been updated and they said that all the phones have been updated.

*****From time to time, after pressing the HOME key, an HTC screen will appear and disappear 20-30 seconds later.****

If you are having some or all these issues, you can do the following: NOTE: 1 and 2 did not fix my hero. I will try 3 tonight.
1. Plug Hero to PC, download and run original RUU (Factory apps, settings etc)
or
2: From your phone: MENU>Settings>Security>Factory Data Reset.
or
3. Install CUSTOM ROM. (This should definetely fix the problem/s.
If everything else fails, contact Sprint Tech Support, I know they will not be able to fix anything, but what they can and will do is; report problems/issues to HTC and Android Developers.
I know what IS CAUSING the YouTube: Cannot play this video issue, but I can't do anything if it's just me talking for everyone.
I will be updating this post/thread so stay tuned.
MERRY CHRISTMAS!
