Whenever my jailbroken iPod Touch has to reboot it'll take upwards of 15 minutes in a cycle of reboots before finally landing on my home screen. Is there a Cydia tweak to prevent this? Won't do it on a respiring, just a boot. Watching the apple logo show up, go away- black screen, logo shows up... goes away. . . black screen. It is annoying as all get out.
