Apple tablet details 'revealed on Twitter'

Apple's tablet is said to be based on the iPhone OS

Details of Apple's much-rumoured tablet device have been publicised on Twitter by Jason Calacanis, founder of technology site Engadget, who claims to have been using a sample unit for the past two weeks.

The device, which is due to be officially announced tonight at an event in San Francisco, is based on a version of Apple's iPhone operating system, with the ability to have multiple applications running at the same time, Calacanis revealed in a stream of Twitter updates from his verified account.

A verified account is a Twitter feature designed to authenticate that the author is who they claim to be.

However, Calacanis said that he was unable to disclose the official name of the device, variously labelled as the iPad, iSlate or iTablet, as this is still under a non-disclosure agreement.

Other specifications include Wi-Fi and 3G data connections, with both Verizon and AT&T listed as carriers in the US by Calacanis. Also mentioned are two "thumb pads" on either side for "mouse gestures", plus two cameras, one front facing for video conferencing and one at the rear, presumably for capturing video or stills.

Apple has also built in an e-book reading mode, which appears to confirm earlier rumours that the company is going after the electronic publishing and entertainment market with this device.

Calacanis also said that the device can connect to other tablets using its Wi-Fi connection for multiplayer gaming, and will cost $599, $699 or $799 (£369, £430 or £492) in the US, depending on screen size and configuration.

A spokesperson for Apple UK told V3.co.uk that the company was unable to verify any of the details disclosed as genuine, and said that the information was simply rumour and speculation as the company has yet to announce anything.
