Hiding in the code of the iPhone app, it's Facebook for iPad.
iPad fans have been waiting for an official Facebook app for going on 18 months now one tech blogger appears to have unearthed the app - hidden within the code of the official Facebook application.
MG Siegler of TechCrunch delved into the back-end of the iPhone app and found a fully executable version of a Facebook iPhone app which he was able to load onto his device.
Siegler, who has been testing out the new, yet-to-be-announced application on his iPad, reckons it uses the tablet format to offer a completely new navigation system, with a menu on the left hand side of the screen. He also reports that when you flip the iPad horizontally your friends lists appears so you can chat with them using the site.
Places arrives in the shape of a big map, on which you can view all of your friends, and the photo viewing experience to that of the iPad's own photo app, according to Siegler.
Facebook is yet to confirm if and when it will be launching an application for iPad, and it's not yet certain whether this will be the version that arrives on the App Store, but you can see a host of screenshots of the hidden Facebook for iPad application here.
Kudos to Mr Siegler. That's some mighty fine detective work.
