One reason we love Android OS is the availability to have widgets on our home screen.. sorry iPhone owners. Our friends from XDA develpers get the System Dump of the new LG Optimus 2X. Now we can install many of its widgets into our phones. Personally I installed a few of them in my Captivate and they run very good. One is the Weather Widget. It tells you the weather, temperature, time and date. You probably need a whole new home screen to install it and use it. However, if you use a Launcher like Launcher Pro, you can re-size the widgets and have some extra space for another shorcuts.
Just download the file and install into your phone. You dont have to be rooted, you only need to have access to install non Market applications.
Do it on your own risk.
