iPhone OS 3.1.3, 4.0 Undergoing Field Testing?

iPhone OS 3.1.3 and 4.0 are apparently already in field testing according to a web site’s access logs. The Boy Genius Report web site shows devices with iPhone OS 3.1.3 and 4.0 firmware connecting, alongside hardware at or before the present v3.1.2 revision. A v3.1.3 release could be imminent, as it would be a relatively minor update and just in time to support a flood of new iPhone and iPod touch owners.

The iPhone OS 4.0 firmware is not expected to become available for some time, as Apple normally reserves major updates for the debut of new hardware, preceded by a press announcement months in advance. The next announcement is most likely to occur in the first quarter of 2010, ahead of a fourth-generation iPhone shipping in June or July.

Upcoming features remain uncertain, but should include Google’s Maps Navigation, which adds turn-by-turn directions to the Maps app on supporting devices.
