Facebook just invited press to an event at its headquarters on April 4th to “Come See Our New Home On Android”. Sources tell us it will be a modified version of the Android operating system with deep native Facebook functionality on the homescreen that may live on an HTC handset. The evidence aligns to say this is the Facebook Phone announcement people have been speculating about for years.
