There does not seem to be individual settings for the Google+ iPhone app, which means if you never want your location attached to an update, you will need to turn it off every time.

One part of the Google+ iPhone app that needs tweaking is the interaction with posts in your streams. Unlike Facebook's iPhone app, there are no buttons within your streams that let you comment on, +1 or mute someone's post. Instead, you need to tap the individual's post, which will take to you a new page, in order to comment.

This new page includes a +1 button at the top, as well as a drop-down menu at the bottom with options to mute or report the post. One big feature that is missing: the ability to share posts from within the app.
