so i just upgraded and i noticed that when i make calls or when i get calls, the screen background is BLUE. is there anyway i can change the background and the font and color on the caller screen? oh and is there anyway to get rid of those annoying black squares by the time stamps in the sms texts? annnnnd my blackberry messanger dissappeared.. even when i tried to load it on the desktop manager it said succsessful but it was no where to be found!
