What kind of physical defects that you guys have found on Diamond?

[Procter]

I'm about to get one and I need some info from you guys so that I could find out if there're defects on mine or not.

From what I've read, there were at least four problems reported:

1. Battery drain extra fast
2. Extra HOT when using extensively for youtube or other data app
3. White spot on screen
4. Rainbow pattern on screen just like my old Touch

Again, I found some inconsistency in handsets, some users said that without extensive usage, their battery could only hold for half a day; while others claimed no problem for a day. Is there any trace to identify which one is with better battery? Is this a hardware related or can be fixed by firmware update?

Another thing that I care most is the screen, my touch has a super crappy screen, with limited viewing angle and the rainbow pattern. While only a few lucky dogs got their hands on a good screen. (sth like the Verzion version, I've seen the difference). How is diamond's screen? Any known problems that most of you have on your handsets?

TIA
