Meg, on the iPad, none of this works. Settings etc simply sends you to Google's whole privacy policy. Mine claims they don't have a location for me, since I have Safari location OFF, and indeed, there is nothing in the location part. Here's what it says. Get this. "WE HAVEN'T PROVIDED A WAY TO TURN OFF LOCATION CUSTOMIZATION":
Location Turn Off (my words, the rest is theirs)

"The customization of search results based on location is an important component of a consistent, high-quality search experience. Therefore, we haven't provided a way to turn off location customization, although we've made it easy for you to set your own location or to customize using a general location as broad as the country that matches your local domain.
If you find that your results for a particular search are more local than what you're looking for, you can set your location to a broader geographical area (such as a country instead of a city, zip code, or street address). Please note that this will greatly reduce the amount of locally relevant results that you’ll see."

So it appears they are going to use your IP whether you like it or not. And this is a Safari/Apple follow-the-money issue, as far as I'm concerned. This looked as though it was revised last month. If there's a way around it on the iPad, I'd sure like to know! Thanks much for your help.
