This morning, after I setup a new Microsoft Email exchange email account, my iPhone magically erased "Never" option in Auto-Lock setting and I got a notification to change my passcode. iPhone is still on Jailbroken Firmware 6.1. I disable Auto-Lock sometimes because one cydia plugin is causing iPhone to reboot everytime it goes to sleep/lock mode.

Did Apple somehow updated my iPhone firmware setting? Or could it be because Microsoft Exchange?

This is weird.

Ok nevermind, my company must have Never option disabled somehow. I deleted the new Exchange email and got my option back.
