Next iPhone codename revealed in newest SDK

With iPad buzz out and about, those worried that Apple might be slacking on building its other product (yes, the iPhone) may now breathe a sigh of relief, at least for now.  The latest iPhone operating system 3.2 SDK reveals that the next iPhone is currently in the works, specifically, the codename of the new iPhone, the "N89".

According to some tipsters over at Engadget, it's "likely the codename of the next iPhone (previous versions were called the M68, N82, and N88)".  Also may be true is the new model "N80" included in Apple's released 3.1.3 firmware, which may very well be the new iPod Touch codename.

We'll keep you updated with anything else we find.  Any thoughts what the N89 or N80 may come out with?
