Apple has just released the latest delta update to iOS 7. Version 7.0.4 is now available to download. Head to Settings>General>Software Update on your iPhone, iPad or iPod touch and it should show up. It’s a relatively small file at only 37.4MB and won’t take long to install. In the description it states that it’s all about bug fixes and improvements. Most noticeably was a bug that caused FaceTime calls to fail regularly.
As a sort of side note, anyone rocking an iPod touch 4th generation will be pleased to know that Apple has also released iOS 6.1.5 just for you.
