Does the latest Windows Phone 8 prototype image leak show the Nokia Phi?

Another image of a purported Nokia Windows Phone 8 device has surfaced, this one showing what appears to be a prototype of the rumored Nokia Phi.

"Phi" is widely believed to be the code name for Nokia's first Windows Phone 8 device, expected to be revealed at a special event on Sept. 5.

The new image follows another leaked earlier in the week, that one from Nokia subcontractor ALPS, which handles some of the Finnish company's phone development.

The two images clearly show bezels from different devices, though, which begs the question: just how many handsets will Nokia will be revealing in September?

Three of a kind

The 4.3-inch bezel displayed in the earlier leaked image features curvier corners, distancing it from Nokia's Lumia 800 and Lumia 900, despite the similarities in size.

On the other hand, the screen in the most recent leak shows something closer to 4 inches, though in form it's far more in line with existing Lumia devices, including the Lumia 800.

That also makes it all the more likely that it's an image of the Nokia Phi, which is rumored to be a next-gen replacement for the Lumia 800.

So that makes two new Windows Phone 8 devices at least, if all the prototypes we've seen so far come to fruition.

But could there be a third, even larger device - one to rival Samsung's Galaxy Note?

"Samsung, take note"

Chris Weber, Nokia's executive VP of sales and marketing, took to Twitter on Thursday to let off some steam by taunting Samsung.

"Samsung, take note," he wrote. "Next generation Lumia coming soon."

His innocent jab may be just that, but to some it seems Weber was hinting at something: the impending arrival of a Nokia tablet/phone hybrid (or "phablet") to rival Samsung's 5.3-inch Galaxy Note.

It may be a stretch, but between Weber's tweet and the two disparate prototypes hinted at by various leaked images, all three of Nokia's rumored upcoming reveals may already be known by the time Sept. 5 rolls around.
