This isn’t just any photo of a plate of sushi.

Although the EXIF data for this photo says it was shot with an iPhone 4, the rest of the data says otherwise. According to the data, it was shot with an 8-megapixel camera, as it originally had a resolution of 3264 x 2448 before being cropped to a 5.12-megapixel size of 2235 x 2291. It’s also fishy that the photo was taken at 4.3mm f/2.4, which is decidedly more point-and-shoot-like than the 3.85mm f/2.8 lens setting of the iPhone 4.

The last bit of proof that this shot wasn’t actually taken with an iPhone 4? It’s geotagged location is none other than the first building at 1 Infinite Loop, Apple’s headquarters.

You know the rumors. The iPhone 5 is expected to have an 8-megapixel camera, an A5 processor and a slightly larger, flatter form factor . Previous guesstimates had the newest iPhone coming this month, but it looks like we’ll see the iPhone 5 in October, and it’ll be available on Sprint in addition to Verizon and AT&T.

Caveats: It is possible the EXIF data isn’t entirely truthful. The photo also could have been taken with just about any prototype Apple device — like that iPhone 4S also rumored to debut at the same time as the iPhone 5.

Regardless, the photo looks great. So does that uni.
