It seems inevitable (and sensible) at this point that BlackBerry will soon be launching Android-powered smartphones in an effort to save itself. According to a new rumor, the first will be called the BlackBerry "Venice," and it will be exclusive to AT&T in the U.S.

"The Android-powered BlackBerry Venice slider is AT&T-bound," claims reputable leaker Evan Blass (@evleaks) on Twitter, alongside the picture above, which shows a BlackBerry Passport running what appears to be a custom Android OS.

The Passport isn't a "slider," of course, and this is almost certainly an unofficial mockup (the screenshot doesn't line up properly with the display). But it's unclear whether it's intended to be a representation of an upcoming BlackBerry with Android, or just a jokey teaser.

According to a recent report from N4BBthe Venice will be a high-end BlackBerry handset — better than any of the BB10 devices we've seen so far — with a 5.4-inch Quad HD display, a 1.8GHz hexa-core Snapdragon 808 processor, and 3GB of RAM.

The Venice is also expected to have an 18-megapixel camera on its back, and a 5-megapixel camera on its front. N4BB says the device will make its debut by this November.
