Lockscreen feeling a little boring? Why not toss the whole thing out and try something different? Many third-party lockscreens are a bit awkward and lack features, but SlideLock seems like it does some cool stuff. SlideLock stands in for your stock lockscreen and replicates the notifications from the notification shade so you can deal with them without unlocking the phone.
SlideLock has a clean interface with a clock, date, and custom (optional) status bar.
