TechnoBuffalo is quoting a "very well positioned source" this afternoon saying that Sprint's event with Motorola early next month will be for an Android-powered smartphone known as the Photon 4G. As you might expect from the name, WiMAX is on board -- and we're also told to expect other specs that put it roughly in the same league as the Atrix 4G and Droid Bionic: a Tegra 2 dual-core processor, 1GB of RAM, an 8 megapixel camera, 4.3-inch qHD display, and a rear kickstand with a target ship window in July.

Separately, we're being told that the event will likely be for a Tegra 2 phone with a large touchscreen and no physical keyboard codenamed "Sunfire" that features WiMAX along with GSM compatibility for global roaming. Putting two and two together, you can imagine that Sunfire is very likely the same phone as the Photon 4G. Wouldn't it be wild if the Photon ended up beating Verizon's Droid Bionic -- which, you might remember, was announced way back at CES -- to customers' hands?

Also of note: the event invite says they'll be showing their latest "collaborations" -- plural -- which suggests the Photon isn't the only device that'll be in the mix. A WiMAX version of the Xoom is an obvious candidate, though our tipster believes the project is still a ways off... if it ever hits the market at all. At this point, a new tablet (perhaps at a different screen size) might make sense to make Sprint's launch more compelling, especially considering that the WiFi-only version of the Xoom has already been in Sprint stores since early this month.
