ConceptLS for iOS7 is the most advanced lockscreen available. I could easily write a 4 page description on this, but I will not. You can find that on JunesiPhone.com.
Features: Tap to unlock, LS Dim is set to 20secs (instead of 5), Touch and Swipe gestures, Open Apps from the Lockscreen, Sounds, Light/Dark (Changes all items to white or black), Bytafont 2 support, Complete package is less than 2mbs, Help Screen (to show touch points/gestures), Weather such as Temp, Description, Ext Description, and Weather Icon.
NO FILE EDITING.
Settings from the lockscreen: Wallpaper set from actual CameraRoll (very easy, no lockscreen has this), 12/24 hr time display, Celsius or Fareinheit, Zip/Woeid entry (To set your location no GPS).
Tweak used to hide elements Lock Screen Tool.
