Two new iterations of iPhone firmware are already in field testing, a website's access logs indicate. Records publicized by Boy Genius Report show devices with v3.1.3 and v4.0 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.
