Popular analyst for Piper Jaffray, Gene Munster, has speculated in a note to clients that Apple could be planning an event for the end of June or early-July. The event would mark the return of Steve Jobs and the launch of a new iPhone.

The note from Munster followed Apple’s press release regarding the WWDC opening keynote on June 8th. “As indicated in today’s press release, we believe Apple will focus on the new version of Mac OS X 10.6 Snow Leopard at WWDC,” wrote Munster continuing, “While some investors may be expecting Apple to launch redesigned iPhones at WWDC, we do not anticipate the launch in early June.”

Additionally Munster adds that an event held later in June or early-July could usher in a “family” of iPhones. “We continue to expect multiple models, possibly a high-end iPhone with improved specs from the current version and a low-end version with lower capacity and fewer features along with a reduced pricing plan,” wrote the analyst.

On the other hand Daring Fireball author John Gruber has come out to describe Munster’s claims as “goofy” adding that a new iPhone model at WWDC was “probably the easiest and most obvious Apple prediction of the year.”

Gruber’s comments don’t come without valid reasons, the blogger writes that if the new iPhone is to incorporate a magnetometer and video recording as per the rumours then that would require “new APIs, and if Apple wants to have WWDC sessions for the new hardware-specific APIs, they have to announce the hardware first.”
