iOS 7.0 Beta 4 is available for download

I just updated my iPhone 5 over the Air - the download is about 230MB and the update process takes less than 10 minutes. 

I have seen only small changes so far. You can find the Release Notes on the Developer Site or here:

Obviously this release includes for the first time code for the mysterious fingerprint reader that should be part of the next iPhone hardware release.
