[2.1 — Mac Pwnage] All apps start crashing, need multiple restarts to sort
I've been an exceedingly annoying problem on my iPhone since 2.1.
Every few hours, most applications start crashing on launch. It's always a random subset — Mail, Cydia, iPod, Safari and others will crash, but I can launch BossPrefs and reboot.
Post reboot, I notice Cydia, Settings, and Maps crashing... and BossPrefs too. I'll usually only try a few before restarting, but at least half of applications may become affected at any given time.
Respringing never helps. After a reboot, Mobile Substrate sometimes goes into safe mode, and sometimes the entire system freezes for several minutes at the lock screen before I can start using it.
After four or five reboots the system comes up normally... and the crashes start again after a few hours.
I have restored multiple times, rebuilt my IPSW in PwnageTool, and restored without restoring from backup.
I've even observed Cydia crashing ON THE FIRST BOOT AFTER A RESTORE, before iTunes has even seen the device.
WTH?! Anyone else seen this?
