Hi all: I decided to do the jailbreak today using redsnow. Everything went great, however, when I tried to install an MMS app from CYDIA everything went wrong. After it installed the package, I pressed the button to reboot my phone like it asked. After that point it began to reboot, but has frozen at the apple logo bootup screen. I've told it to rest by holding own the top button and the home button, but it just restarts and freezes at the same place. It won't show up in itunes for a full restore and i can't get it into DFU mode. Thoughts?
