Could you please tell me how you put the LS Swap modded for your springboard? I've been looking to see how you put the time on the springboard like that.
In Cydia there is a package called iPad LS Swap. I used iFile and renamed the LockBackground.html to Wallpaper.html. Then went into the style.css and scrolled down past #swap-wrapper where it says "top:" and changed the number to 645px.
To change the wallpaper I used my own image (768x1024) and renamed it ipad-wall.png and put it in the Images folder. Respring and voila...springboard clock.
