Apple CEO Steve Jobs unveiled a suite of new iPhone applications at yesterday's MacWorld keynote address in San Francisco.  While the new software adds several useful features to iPhone, several of them should look familiar to users of "Jailbroken" iPhones - we've been rocking this "new" functionality now thanks to tireless developers in the iPhone hacker community.

Faux-GPS powered by cell phone tower and Wi-Fi triangulation?  Available as "Navizon" on Jailbroken iPhones.  The ability to customize your home screen?  We call it Summerboard.  Text messages that can be sent to multiple recipients?  SMSD handles that.

Of course there are a few new goodies like Web Clips and iTunes support for manual media management, lyrics, and movie rental.  And everything is wrapped in Apple's slick UI and blessed with its seal of approval (read: No hacking required), so it's not like there was no news at all.  But Apple does have a long, under-publicized history of offering up "new software" after it's caught on in the open source community.  Coincidence?  Theft?  The good business practice of giving people what they want?  I'll leave that to you to decide.
