Android: GOTO Lockscreen is a replacement for Android's built-in lockscreen with some very smart functionality built in.
GOTO Lockscreen is very simple to implement with its built in setup/tutorial, so once you download it, you should be up and running in a minute or two. Once installed, you can see immediately how this app is going to save you time. The normal unlock slide function of your Android phone is now replaced with a very stylish arc based slider that has a few other tricks up its sleeve.
GOTO Lockscreen costs $1.53 in the Android Market.
