Apple has released a new beta of iOS 6 to developers for testing. The update is currently available in the dev center, or via an OTA delta update. The update prompt mentions only “bug fixes and improvements” .

The over-the-air update weighs in at 347MB for iPhone 4S users, and 424mb for iPad 3 users.

So far, iDownloadblog has identified one new feature, a brand new item in Settings dedicated to preferences for Apple’s own Maps application.

Once in Maps settings, you can choose between miles or kilometers for units labels, as well as set your desired language, label sizes and turn-by-turn navigation volume, independently of the system volume.

Another subtle tweak discovered by 9to5Mac: Safari now displays nice icons for bookmarks, reading list and history in place of worded labels. Plus, Safari on iPad feaures a handy syncing progress indicator right below the reading list icon in the toolbar.

Apple is expected to release the final version of iOS 6 this fall.

We will keep you updated if there is anything new discovered.
