Updated version of app that allows you to control when your winmo6.5 lock screen comes on.
(I only found posts of an older version, so sorry if this is a repost.)
AutoLock Screen v1.7E (also attached for convenience)
(from:
http://thewingster.com/autolockscreen.aspx [more info there])
It uses the native winmo6.5 lock screen.
Just install the cab.
I just tried this out on EnergyRom build 21877. After a soft reset worked like a charm. It puts an icon in start ->settings -> system called "Smart Lock". Using that you can control when the lock screen comes on.
I have mine set for after reboots and for after I turn my phone screen back on. But there are a few other settings.
