We have 2 EVO's-one is still plagued with GB issues, one hasn't had them yet. Mine has been fairly stable for a week now, although on Thursday when I turned it on, it gave me the colorful bubble background. Friday when I turned it on, it gave me the black slate again. I finely got brave and used the camera in lowlight to see if it would freeze. It didn't, but I swear when you use it for the first shot it always makes a little sizzle, spark like, static like noise. Suppose that goes along with what people have been saying, it's a power management issue.
Still seeing the GSP showing active after I turn it off problem. Should say, when I turn it off with the power bar. I added the GSP icon and I think, clicking on it to turn it off vs turning it off on the power bar works most of the time.
While I say I have been stable for a week, I only have a few icons on my desktop, never hooked myself back up to wifi, only used the GPS to find a place to eat twice and only used the camera once to see if it would freeze. So very limited usage of anything.
If I had to do it over again, I would've lived without the GB update as the phone had been 100% perfect for the year before it. Good luck deciding.:'(
