Last night I was trying to remove CityID from my LG8575. (I know its old but I like it.) It came up when I had to do a system restore on the phone.
I just went round and round with Verizon's phone Tech Support telling me to "highlight CityID" in Media Center and choose "options". But everytime I touched "CityID" it opened the app with no "options" ever displaying.
I just found the secret trick. Go to MediaCenter - Browse & Download, there you should see "CityID." To the right of the name on the same line is a grey icon with a white dot in the middle. Touch that icon and up pops the options menu. Then choose "Remove." And away it goes.
Neither Verizon CS or Tech Support seemed to know, they just kept saying "Highlight CityID" and then didn't know why the "options menu" didn't come up.
