I set the Autolock option to 'never' earlier today so the phone didn't turn off during a download, but now the Autolock option has completely disappeared from Setting, General, and I can't set it back so it autolocks. Just to be sure this is clear - the whole Autolock option has gone.
Any ideas why it may have gone and if there are any methods to get it back?
Have you tried rebooting or restoring it? If that doesn't work you could download autolock toggle in cydia for sbsettings and see if you can turn it on/off that way.
Tried rebooting and dare not try a restore! SBSettings didn't fix it but Autolock option in BossPrefs does work - so at least I have a workaround. Thanks for the suggestions.
If anyone knows how to get the proper option back in Settings General I'd still love to know.
