I just jailbroke 4.0 via jailbreakme.com. All went well, but during the reboot I noticed something i never saw before. When on the boot up screen with the silver apple I saw a weird multicolor line on the top right corner and I saw the "loading wheel" on top of the apple. It booted up just fine though. The line and the wheel shows during bootup now. Is this normal with a jailbroken 4.0?
