Apple today has quietly released iOS7 beta 4 for developers, bringing "bug fixes and improvements” to the iPhone, iPad, and iPod Touch.
Although I haven't gone hands-on with the new OS, I hear that each new update brings more improvements infunctionality and core usability in preparation for its suspected official launch in September.
If you haven't yet updated, grab the OTA on your UDID approved device now.
