The Acer beTouch E400 was officially announced at the Mobile World Congress in February 2010.

The E400 is powered by the 600 MHz Qualcomm QSX 7227 CPU and runs the older Android 2.1 Eclair.

It has an 81mm (3.2-inch) touchscreen, a camera without flash, Wi-Fi, geo-tagging, digital zoom, scene modes, white balance, color effects and a simple macro mode.

It supports Native Microsoft Exchange Server and a Shareware "Documents To Go" application that can edit and create Microsoft Word documents, Excel and PowerPoint and Adobe PDF.

The beTouch E400 comes preinstalled with Acer Sync, a smart application that allows automatic cloud-based and Wi-Fi synchronization with netbook, notebook or desktop.
