ACER F900 is another WinMo 6.1 touchscreen phone from Acer with their special user interface. Just like M900, F900 also comes with a big 3.8″ screen and high speed connectivity.
The rest of the specs is pretty much the same such as the 3.2MP auto-focus camera with flash, GPS, FM Radio, voice recorder, voice command, and expandable memory. However the difference comes in with the installed applications: Internet Explorer 6 supporting JavaScript and Adobe Flash Lite. Also Acer calls F900 a 3.75G phone (HSDPA/HSUPA). There’s Wi-Fi too of course.
