How to change Android Lockscreen

Are you bored of the lock screen which comes built in to your Android phone yet?  If you want to change that then you need to get an app There are various such apps available in the Android Market; such as:

LockBot

LockBot

LockBot is one of the most comprehensive lock screen apps available for Android phones. The app has some amazing features to offer. However the app still needs some finishing and lacks quality at present.
In the free version you get three lock screens: iPhone, Hero and Eclair styles. The pro version has Froyo, X10 and Galaxy styles. Also in the Pro version you can access the theme gallery and choose from the various themes available there.
You can either select either one particular lock screen type or more than one style. When you select more than one style the lock screens will change each time you lock your phone. The app also allows you to edit the clock and backgrounds of each lock screen.
Overall, it is a nice app; however, it’s priced at $3.49, which is very high compared to the rates of other similar lockscreen apps.

WidgetLocker gives you the total control of the look, feel and layout of your lock screen. You can choose the widgets and shortcuts  you to place on your lockscreen, allowing you to access them directly from it.
A unique feature of this app is the custom sliders. These sliders can be used to do a particular function like open the dialer or turn on the flashlight. This feature makes this app stand out from the rest of the lockscreen apps.

WP7 Lock

WP7 Lock is currently available for free as a lite version. Customization features are not yet available in the app, but the app works fine and brings to your Android a lock screen very similar to that available on phones running Windows Phone 7. It shows the message and email count, and also the number of missed calls (if any).

Screen Suite

This is a very well-built lock screen replacement app. Yes, it has an iPhone style unlock slide bar, but it puts an Android twist on it. It also includes a contact card in case you lost your phone.
This app gives you three lock screens; one displays owner information, the second displays the date and time, and the third shows the battery level. You have an option to choose between iPhone and Android Bot style slider.
Overall, a very nice app and definitely worth the money.

GOTO Lockscreen

This lockscreen has a very different design and definitely stands out from the others. The lockscreen slider has four icons: Messaging, Call Log, Gmail, and Unlock.  When you move the slider arrow over an icon, you get a preview; when you release the arrow you are taken directly to the app.
The lockscreen also displays the number of new SMS messages over the text message icon and unread email over the Gmail inbox icon.
