The Liquid A1 is the first Android phone made by Acer in 2009. It launched with Android 1.6 but now an update is available to bring it out of the Dark Ages and into the Light. The update is the usual OTA variety, so if you're one of the folks out there with the device, hopefully you'll be receiving the notification soon enough.
The Liquid A1 has a 3.5-inch touchscreen and 5MP camera with VGA video. It features a 1GHz Snapdragon processor, but it's underclocked to 768 MHz. It has 256 MB RAM, HSDPA 7.2 connectivity and HSUPA 2.0 Mb/s. You'll find the general stuff, too: WiFi, GPS, Bluetooth, and microSD card slot. If you get the update, let us know in the comments and let us know what you think of it.
