Hey guys I have been using the LG Optimus 2x Smartphone with Android 2.2 Froyo in it from last 15 days. This is one of the best mobile phone that I have come across in my life which I have used. It is just amazing and performance wise also it is very good. Before, I was able to connect my device to my computer with Windows 7 OS in it, by using the USB cable which came along with the cellphone. But yesterday, I unknowingly disconnected my phone which was connected to my computer without turning off the USB mode and since then I am unable to establish connection between my device and my system.
