We’ve been tracking down new features in iOS 5.1, and besides the obvious addition of Japanese support for Siri, there isn’t much exciting going on.

Earlier this week, we reported about a subtle change in Safari, which now adds a “go to this address” message in the address bar. Today, courtesy of iDB reader Tyler, we found out about a new feature that’s been added to the Location Services settings…

On your iPhone, if you go to Settings > Location Services > System Services, you will see that a new icon has been added for apps that use a geofence.

Up until now, you could tell what apps were currently using your location, but you couldn’t tell them apart from those that use a geofence. Now you can!

I’ll be the first to admit that this is a meaningless feature, and while most of us probably won’t even notice this, I’m sure a few of you actually will and will be glad to learn about this addition to iOS 5.1.

As usual, if you find anything new in iOS 5.1, please make sure to let us know.
