got a curve last week and noticed that when I am testing and checkingmessages, that sometimes the screen is brighter than at other times. Is there a problem with my phone? Also, sometimes when I end a call, I hear a noose like I am hanging up on speakerphone once in a while. I am wonderingif I should take it back and get a new one because of the screen issue. I am off to check the crackberry site. Thanks!
