Q:

How to unlock Android phone without the touch screen

I have a Huawei phone with Android installed. The LCD display cracked recently, and as the cracks have spread over whole display over few days, it's now totally uncontrollable.
The phone has a 4 way sort-of-joystick thingy, so when it's unlocked I can still use it. However, once the display turns off completely I cannot unlock it to use it.
Is there some key combination or a trick to unlock the phone without using the display? The phone is not password or key locked, it just requires to slide from left to right.
I have USB debugging enabled, but I have no idea how to use it. The phone is not rooted.
Also, I'm wondering how I'm going to save my phonebook and other stuff.
The device name is Huawei U8500.

You can use a USB cable and buy a USB mouse so that you can use that [a mouse] instead of touch screen. Check out a USB adapter for Android that fits your budget [and make sure it's compatible with your device] and purchase it.

Advices

Install a VNC Server on the Phone such as This one, and install a Client on a PC such as This one, and connect the PC to the phone and then you can use the phone on the PC directly
