While many are still worried about the open data door in iOS 6.1.3, Apple issued an update for iPhone 5 owners that upgraded the audio for the speaker phone.
The update iOS 6.1.4 is named Build 10B350, and it is 11.5MB. Many believe there will be no more iOS 6 updates because Apple is expected to announce a new iOS 7 at the World Wide Developers Conference in June.
