Apple unsurprisingly appears to be ramping up activity on iOS 7.0.4 as the next version of iOS to see a release to the public, with MacRumors seeing increasing numbers of devices running iOS 7.0.4 from Apple's networks showing up in web logs



From MacRumors:

Visitors to MacRumors.com via Apple's networks from devices running iOS 7.0.4 The first signs of iOS 7.0.4 appeared on October 22, the same day iOS 7.0.3 was released to the public. Activity has been ramping up over the past two weeks, but there is no word yet on when the update might be released to the public. Apple has also not seeded registered developers with any builds of iOS 7.0.4, but the company does not always do so for its minor iOS updates.
