Facebook is set to introduce an iPad compatible version of its Messenger for iPhone app, among other announcements, at the company's 15 January media event, according to sources in the know. 

Messenger for iPad's features are said to include emoticons, the ability to share photos, location tagging, group messaging, and read receipts, according to a report from TechCrunch.

The new voice-recorder messaging feature unveiled this month for the Messenger iPhone app is also tipped to be making an appearance.

Facebook invited members of the press, including Pocket-lint, to the media event at its headquarters and to a simultaneous event in London to "see what we're building". The company didn't hint at what is to be announced, but a Facebook phone of some-sort has been rumoured to be the star of the show.

Mark Zuckerburg and Co are notorious for being slow to introduce iPad apps, with hit photo-sharing service Instagram and Facebook Poke still being iPhone only. There's no word if either will be highlighted at the event alongside Messenger, which has been available since August 2011. 

In May, 9to5mac obtained a working version of Messenger for iPad, complete with video chat capability.
