Recently I installed and uninstalled a few Cydia apps have have sense had some difficultly. I believe it was the recently release Advanced Preferences that did me in... I have a 3Gs with 3.1.2 jailbroken with Blackra1n. When I reboot the phone I don't see my lockscreen and springboard loads up. When I try to open any app, except one, they all blink like they are going to open but don't. The notable exception is the phone and when I close the phone the lockscreen then shows. Seemed weird but I turned on the syslog SBsettings add-on and I see the messages below after reboot when attempting to open the app. Dec 14 02:36:46 iPhone SpringBoard: Attempted to activate application com.apple.mobilecal while device locked Dec 14 02:36:48 iPhone SpringBoard: Attempted to activate application com.apple.weather while device locked Dec 14 02:36:54 iPhone SpringBoard: Attempted to activate application com.saurik.Cydia while device locked Dec 14 02:36:56 iPhone SpringBoard: Attempted to activate application com.saurik.WinterBoard while device locked This shows a mix of official Apple apps and Cydia add-ons. As you can see from the messages apparently the lockscreen does load, it just doesn't show. Pretty sketchy. I could live with this but a side effect is that the phone no longer locks unless I press the power button. Yes, I know this is a valid work around but there are times I forget to do this because the feature to auto-lock should work and I've gotten used to that with the iPhone and previous phones. I've tried reinstalling the suspect app and uninstalled it as well as uninstalled apps and add-ons I installed around this time. I've reinstalled Winterboard and MobileSubstrate but this made no difference. I know what will work, reload 3.1.2, jailbreak and start from scratch but I would like to avoid that if at all possible since it will take a decent effort to get things back to how I have them now. Anyone have any ideas on things I can do to try to fix this without an overhaul? Thanks!
