This is a WM 6.5 lockscreen tweaked to resemble the Manila home tab (to the extent that this is possible). Almost all the hard stuff (the clock font, the clock background, etc) were taken from torsergey's excellent mod, made for Leo (HD2) - available here. Thanks, torsergey.
What I did was the slider, the green bullets on the sliiders, some small alignment stuff, etc..
When uninstalling you might loose the default WM 6.5 lockscreen. To avoid that, please make sure that you backup your original /Windows/LockScreen directory and restore it after you uninstall this mod.
This was tested with Miri's latest ROMs - it should work with any ROM that contains the HTC modifications to the lockscreen.
