The Google+ Mobile App (for iPhone) has been tweaked and redesigned since its initial release rather dramatically. The layout now adheres more to standards that are shaping up among app designers, and the sections have been renamed to more accurately reflect what they contain.

When posting on Google+ from the mobile app, you can choose from a list of icons at the bottom of the screen to add content, such as you location or a Web link.

Paying attention to detail, Google's mobile app for Google+ now supports animated GIFs (it didn't previously), giving you the full effect of the fun content people are posting.

Google+ Mobile App (for iPhone) has a section called Communities meant to attract likeminded people.
