TapToUnlock7 by drewsdunne lets you unlock your phone by tapping the screen instead of sliding. This theme lets you tap a stylish 'apple' instead of text.

Don't bother downloading this if you haven't purchased TapToUnlock7 (it's only $.99 you really should do it if you don't like sliding).

To use the 'appleTap' image, go to General > Settings > TapToUnlock7 and use the following settings: Disable Default Unlock = On, Tap Anywhere to Unlock = Off, Hide Chevron = On, Use Image = On, Border = Off, Custom Text = On or Off (it does't matter), Change Hex Color = The color of the 'appleTap' image . Use '&ffffff' to display a white apple like in the screenshot but you can change it to any color that looks good with your wallpaper. Opacity Slider = The brightness of the 'appleTap' image. Use about 50% for dark wallpaper or 100% for very light wallpaper. This will make it bright enough to see but not bright enough to burn holes in your eye ball.
