Today at their mobile event in Palo Alto, CA, Facebook CEO Mark Zuckerberg revealed something interesting and rather humorous. It&'s no secret that Facebook&'s Android app has long been sort of a lame little cousin to their excellent iPhone app. But do you know why Well it&'s mostly Google&'s fault. You see, they acquired the developer Facebook had hired to make the app.

&''Yeah, I thought that was obnoxious,&'' Zuckerberg said today when we asked him about it following the event. Everyone in the room burst out in laughter at that.

Zuckerberg said it was a really small shop that Facebook had contracted to make the app �a4���a4� he was quickly corrected that it was actually more like one developer. &''But it was the main thing they were working on. It wasn&'t like it was some shop and that&'s why Google had to buy them,&'' Zuckerberg continued, clearly still holding a bit of a grudge about it.

&''Obviously, it wasn&'t a huge deal. But it definitely set us back for a while,&'' he noted.a4s��Zuckerberg said that they worked out an arrangement to use the code the developer had written for the app up until then, but that he obviously couldn&'t work on it anymore.a4s��&''It was kind of frustrating.&''

Previously, it was thought that Google was actually helping Facebook to build their Android app �a4���a4� after the social network indicated it wasn&'t a priority. But this makes more sense as to why it was so bad for so long �a4���a4� Google screwed over Facebook on it.

Robert Scoble recorded the entire conversation, so you can hear it in Zuckerberg&'s own wordsa4s��here (it&'s about 32:20 in).

Facebook is finally building the Android app in house now. And they actually updated it today which a range of new features to match the other versions available.
