RIM hasn't even officially announced the BlackBerry Z10, one of its first BlackBerry 10 handsets, but there are plenty of people out there who already own the device. One site that already does own a device, TelekomPresse, recently put the Z10 head-to-head with an iPhone 5 in a 7 minute video.

We're treated to a quick walk-through of how the phones stack up against one another in terms of size, and then the phones are both powered on. TelekomPresse walks us through a BlackBerry 10 voice controlled feature that appears to compete directly with Siri, and is something we haven't yet seen before. We also see how the notifications in BlackBerry Hub stack up against the alerts in iOS 6, Twitter, the Web browser and more.

We're just nine days away from RIM's official announcement, and we can't wait to bring you our own head-to-head videos. In the meantime, be sure to check out our in-depth preview of BlackBerry 10.
