I suggest taking it to Sprint and have them replace it. I did the OTA update on Monday, before it was pulled and I had problems with the vibrating notifications, battery life sucked, phone was freezing, etc. So I took it to Sprint today and they gave me another brand new EVO, saying there was a virus in the update software! I'm not sure if I want to do the update again even though they assured me this new one is fine but I'm happy they replaced it. I bought mine on launch day so I only had til the 4th to return it and this new one seems to be working just fine now. Vibrate works, screen isn't laggy anymore, etc. Hope this helps those of you still with issues after the Monday update.
