I downloaded that driver, installed it (went fine) but when you go into Computer (Windows 7) you do not see the phone like I did previously. When I go into the control panel I don't see it either. It used to pop up as device unknown but now that the driver is installed... it doesnt show up. The device does show up on control panel - devices and printers but I can not open and see the files? I tried to right click and tried to browse files but it give me the device name in light grey showing you can not click on it. The device manager says it is working properly??
I hate to jump in here late and ask what is probably a stupid question, or two, but here goes; do you have usb debugging turned on in Manage Applications/Development? and do you have the "usb storage" turned on?
