First off, I'm running ios4 on a 16 GB iPod touch 2g. I recently jailbroke the device using redsnow beta 4 and it has been working fine. However, i noticed that i can no longer reply to an email. As soon as i hit the arrow, the screen goes blank, and the app crashes. I've restarted and the it still does the same thing. Is anyone else experiencing the same problem? Any ideas on what is causing this?
