For those that missed the news late last week, Facebook is preparing something big for our Android smartphones, and are hosting an event this week to show the world. With rumors regarding their own Android OS skin like the Kindle Fire, a Facebook Phone built from the ground up, or even just a Home Launcher. Today however, we have the hardware details on the actual device.

According to multiple reports, tips, and leaks it looks like Facebook will be replacing the stock Android launcher with their own. Just like TouchWiz and Sense covers stock Android, only it won’t be as deeply intergated. This will mainly function over your main screen and add a few things to the app tray. Just like a home screen replacement launcher.

However, since we already covered those details earlier today, this is about the hardware. If the post and details from AndroidPolice are accurate, here’s what to expect hardware wise from the already confirmed HTC Myst ‘Facebook Phone’.

• HTC Myst on AT&T with 4G LTE
• 4.3-inch 720p HD display
• Dual-core Qualcomm Snapdragon S4 processor
• 5 megapixel rear, 1.6 front camera
• Android 4.1.2 Jelly Bean covered in Facebook
• Sense UI 4.5 (not new Sense like the One)
• WiFi, Bluetooth 4.0, etc.
• and more

This is not the first time we’ve seen or heard the name HTC Myst, and those specs have been tossed around a few times in the recent past too. It cleared the FCC last week with AT&T 4G LTE. However, with the actual Facebook Home APK leaking earlier today attached to this hardware, it makes sense that this will be the first device to launch with the new service.

Essentially it appears that Facebook and HTC are aiming for the mass consumer market and will be offering what is clearly a mid-range Android device covered in everyone’s favorite social network – Facebook. We’re expecting the event on April 4th to reveal this smartphone (with a different name than Myst) Facebook Home, AT&T as the carrier, and hopefully it will be free with a new 2-year contract. We’ll be live with Facebook for all the news so stay tuned.
