As rumored, the DX900 has just been relaunched as an Acer smartphone. The good news is that aside from that phone, Acer has unveiled 3 more smartphones at the Mobile World Congress.

The Tempo line is their new series of smartphones, and aside from the DX900, they also introduced the X960, F900 and M900 as maiden models of their brand new line of Windows Mobile-powered devices.

It's not as impressive as what we were hoping for, but its a pretty safe and decent initial offering for a newcomer in the industry.
