OK so this might be common knowledge, but I had to do a ton of googling to figure it out. So, I thought I might just throw this up here for those looking to replace the HTC slide (down) lock with the Vanilla slide (left) lock, found on the OG droids.
Device: Droid Incredible
OS: 2.2
ROM: stock 2.2, nothing custom
Rooted: rooted using UnrEVOked
Program used: Super Manager (free)
OK, so just open up Super manager>file explorer>go to top level of directory>sys>app> now locate HTCscreenlock.apk>long press>rename>rename to HTCscreenlock.bak>reboot.
You should now have the stock Vanilla lock screen.
