What the f***? It happened to me the 3rd time now. I didn't install any applications today...I just wanted to go to calendar. Right when the window appeared to enter calendar...it quits and then does nothing. Just at the main screen(still working, still able to do stuff) just not able to enter calendar. I thought I could do a SpringBoard restart from SMBPrefs and I did. Since then...the iPod touch version 1.1.4 JB with zIphone restarts springboard at a 5-10 seconds interval. I don't feel like restoring and re-jailbreaking as I have a sh*tload of stuff in it that is gonna take days to get back. How can I fix it? Please help me. I am getting tired of this iTouch thing.
