After I jailbroken my iPhone with jailbreakme on ios 4 n installed ifile and openssh, when it starts up it has an apple logo as usual then it shows up a white scrolling wheel above the apple logo and has a weird coloured line at the top right(length is above half of the screen) is this something I should worry about? Hardware or software problem? IT IS NOT DEAD PIXELS after startup at home screen it shows not even 1 dead pixel. PLEASE HELP!!!!!! IM WORRIED ABOUT MY BELOVED IPHONE!!!!!!
