First post here so be gentle!
Every time I plug in the usb, it fires off my default browser and trys to get me to sign up for Vcast.
From the research I have done, what happens is that the phone does an "autoplay" when it is connected (like any other usb mass storage device).
I have found that there is a file /etc/system/CDROM.ISO which if removed stops this... of course I have no permissions to delete the file.
I guess that means I have to root the phone to stop the endless harassment from Verizon.
Any other solutions?
