I have a Storm and recently upgraded to the 5.0 operating system. Prior to this, when I connected my BlackBerry to my computer, it would see it whether Mass Storage Mode was enabled or not. This was critical for my usage as I subscribe to the Rhapsody music service. One of the features of the service allows me to transfer whatever music I want to my smartphone without having to buy each track (it's called Rhapsody To Go). The service would not work if mass storage mode was enabled. However my computer, and the Rhapsody software would still see the Storm when Mass Storage Mode was not enabled.
Since the upgrade, neither the computer nor the Rhapsody software can see the phone when Mass Storage Mode is not enabled. I've contacted Rhapsody and they have no solution. If the computer does see the device, it refers to it as a Removable Disc. If I try to click on the icon, it tells me to Insert Media,
