Welcome to Google world. Google and Apple have just about taken control of the cell phone market. Unless you have a Google Android phone or a Apple cell phone your locked out of the new world of things. Google wont even allow anyone without the latest android levels login to the app store to download software. My issue is with GM and the Onstar application. Google has the latest version which GM states is required. Google wont allow access to older phones. Even Microsoft phones are locked out.
As for giving info, read the listing and see why they want info.
