I've jailbreaked my ipod touch via jailbreakme.com. After installing some apps, the home screen failed to display the apps installed (including the installer). Thinking that it is some kind of glitch, I rebooted my touch and it now freezes at the apple logo whenever i turn it on. I am unable to go into recovery mode nor can my itunes detect the presence of my touch connected to the computer. What should I do?
