Whenever you have a need to synchronize your Motorola, HTC or Froyo Android phone with Exchange then the chances are that your device is locked with the password. And you have to enter the password each time you want to unlock your mobile phone. This appears very irritating and time-consuming.

It would be best if we can use the Android Unlock Pattern instead of this Keyguard Password Lock which will save us from this cumbersome task. This Pattern allows you to use your unlock screen everytime.
