If Apple's recently-filed patent has its way, then we may be going completely wireless in the near future. An inductive charging dock is depicted in the filing, which only requires a device to be placed inside of it for it to begin charging. In turn, eliminating the need for grabbing a cable while makes charging possible even when returning home after a drunken texting spree. (Disclaimer: iPhone Alley does not condone drinking and texting, however we do condone better-than-modern-sitcom humor...)
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.
