I have recently been issued a 7510 but it came with no software. Our IT dept finally got the device to send and receive enterprise email and calls. However, I have downloaded the newest Desktop Manager but am hesitant to install it due to the problems we experienced in getting the device setup. I am concerned that in installing the desktop software that it would update the device settings. Further, everytime I plug the device into the usb port, it says that it is installing a new device and asks for drivers... where do I find the drivers if I don't install the Desktop Manager...???
