I just upgraded my phone from 3GS to 4. On my old phone I had a lock screen theme that was an Apple Logo and no visible slide bar. I thought it was "BootLogo LockScreen" but I installed that on the new phone and while the boot logo is on the screen, the slide bar is still visible. Perhaps it doesnt work with 4.3.3? Any other themes or tools out there I can load to make my slide bar disappear on the lock screen?
Sure. I'd try something like "Slide to Unlock Killer" or "SnowLock" (both free in Cydia) to start and see if that gets your device the way you want it.
try to use androidlock xt. go to settings>androidlock XT>Change appearance>minimize then sellect tap to open then go back to change appearence and go to the bottom were it says "leave text blank for default" just use the space bar once and itll be blank. youll have to unlock it with the pattern instead of using numbers though.
