if I have a browser window open (firefox or IE) and i plug in my phone about 80% of the time it will crash my browser with no error message just a crash back to the desktop.
Also if the phone is plugged in and i have a browser open and i choose to save an image or something as soon as the dialog box opens so i can choose a location to save it will crash the browser in the same manor
third if i poen a dialog box in itunes like to chang the directory where i want pictures to be synced from it will crash as soon as the box opens to choose a new location.
im not sure if its a phone problem or a usb problem but its annoying as hell and it didn't always happen. I have tried to restore back to before i had the problem but that didn't work.
