Take this with a grain of salt, as it comes from the oh-so-wise mouth of a financial analyst. That being said, the analyst in question did happen to have a quick convo with Apple VP Greg Joswiak, so we’re inclined to put some faith in his “educated guess.” According to RBC Capitol Markets, an iPhone firmware update is coming soon. Among the fixes and updates will be new widgets, iChat, MMS, home networking support, Leopard integration, and location based services. Chances are good that this won’t be a revolutionary alteration to the iPhone’s OS, but rather an incremental update design to address a number of launch criticisms.  Either way, iChat would be a welcome addition to the iPhone stable, and the other updates should put  some of the naysayer’s doubts to rest.
