Android: If you're unhappy with the default unlock mechanism and screen on your Android phone—more than a few users are!—myLock replaces the default unlocker with a feature-rich alternative which includes auto-unlocking and more.
The Android OS, mysteriously, has no option for outright disabling the lock screen. This is a curious oversight given that you can simply tap the power button to turn your phone's screen on and off—on my HTC Hero for example it's annoying to tap the hardware power button on the front and then slide the unlock bar down to unlock the phone.
MyLock allows you to automatically bypass the slider and auto unlock your phone by turning the screen on or assigning the unlock feature to a hardware button instead of a screen swipe. I didn't realise how much pressing a hardware button and then having to use the touch screen to unlock my phone annoyed me until I didn't have to do it anymore! MyLock for Android is free and is available through the Android Market or at the authors' Google Code page below. Have a favourite Android application to share? Let's hear about it in the comments.
