Cervantes Mobile Jorno Bluetooth keyboard for iPad, iPhone 4 & Dell Streak revealed

Bluetooth keyboards seem to have returned with a vengeance, as users of touchscreen devices like the iPhone and iPad discover that a few hardware keys can make all the difference at times. Cervantes Mobile has launched its own offering to the segment, in the shape of Jorno: it folds out to an 85-percent of full-size keyboard and hooks up via Bluetooth.

The company reckons you’ll see a month’s use from a single charge of the battery (it rejuices via miniUSB) and the whole thing measures in at 3.5 x 3.5 x 0.9 inches when folded or 8.5 x 3.5 x 0.3 inches when unfolded. There’s a list of supported devices here, but we’re guessing most will be picking it up for use with the iPhone 4, Dell Streak, iPad and iPod touch.
The Cervantes Mobile Jorno is available to pre-order now, priced at $79. It’s expected to ship early in 2011.
