Rumor alert: bigger, thicker, cheaper, plastic iPhone to come next year.

Holdouts expecting a larger version of the iPhone this year will have to keep on waiting, a new report says.

Citing sources, Japanese Apple-news site Macotakara says such a device is instead slated for next year, and will use plastic instead of aluminum for its body.

Macotakara says the device will sport a polycarbonate plastic enclosure much like the one found on the MacBook and iBook before it. Other rumored details include a 4.5-inch screen, which would be half an inch larger than the one found on the iPhone 5 and iPod Touch; Apple's usual home button; and a $330 price tag that would be a little less than half of the average selling price of the iPhone 5 (without carrier subsidy).

As MacRumors notes, Macotakara has had a mixed rumor scorecard, but it had accurate information about Apple's latest batch of iPods, some two months before they were officially unveiled.
