Interesting info from the Drum It may be the worldâ€™s most popular social network but thus far Facebook has no official presence on the worldâ€™s most popular iPad app.That could be about to change however after technology site TechCrunch reported that one of its bloggershad unearthed code for just such n app hidden inside the iPhone app. Mg Siegler said: â€œYes, itâ€™s real, and itâ€™s spectacularâ€¦ And yes, it really is right there within the codeâ€¦For the past couple hours, Iâ€™ve been using Facebookâ€™s iPad app. Well, I should qualify this. I canâ€™t be sure if this is the version theyâ€™ll actually ship, but based on everything Iâ€™ve seen, Iâ€™m going to assume itâ€™s at least very close to the version theyâ€™re going to ship.â€œIn particular, the navigation system is great. Unlike the iPhone appâ€¦the Facebook iPad app uses a left-side menu system that can be accessed by the touch of a button or the flick of the iPad screen,â€ says Siegler. â€œThe app also makes great use of the pop-overs (overlay menus) found in other iPad apps. When you flip the iPad horizontally, the list of your online friends appears and you can chat with them as you do other things on Facebook. The photo-viewer aspect looks great â€” similar to the iPadâ€™s own native Photos app. Places exists with a nice big map to show you all your friends around you.
