There have been rumors that a larger iPhone could hit the market as early as this summer, but it's more likely you'll have to wait until nextyear at the earliest.
Curiouser still, these new phones will reportedly run on Wind River Linux rather than the new Linux-based version of the Palm OS that PalmSource is working on (probably because the new Palm OS won't be ready until nextyear at the earliest).
Some other researchers are still suspicious of those findings, however, and Dr. Gazzaley of the University of California at San Diego is quick to point out that all of this research is still in the earliest stages -- he's expecting some more detailed findings nextyear when his team expands their tests and begin to incorporate EEG monitoring as well.
