While many consumers are still trying to track down and get their hands on a new iPhone 3G, it seems that Apple is already plowing ahead with a new firmware revision. OS version 2.1 has been seeded to developers and contains a number of enhancements and changes, many of which are focused around the GPS functions. Core location services will be updated to provide information about your direction and speed. Could this signal an impending arrival of some turn-by-turn navigation software or support? We certainly hope so, but we’ll have to wait and see as there’s no telling when this one might reach general release. Word on the street is that Apple has also implemented a beta version of it’s push background notification service in the 2.1 release as well. You all know how much we’re waiting for that… Background notification FTW!
