While the Xperia X10 has been delayed, another Ericsson smartphone has been spotted in the wild looking hale and hearty. (SlashGear) The Ericsson Faith is a "green" smartphone made from recycled plastic and without the use of any harmful chemicals.
It sports a 2.4" touchscreen with quad-band GSM/UMTS/HSDPA. It also packs WiFi, Bluetooth, a MicroUSB port, 3.2 MP camera, 256 MB of flash memory, and a microSD slot. We've got no info on pricing or availability. This is definitely not the prettiest phone in the world; it looks kind of thick and bulky in these shots. However, the front-facing QWERTY keyboard is done well and there's nothing offensively bad about this mobile's design.
If you want to go green without giving up your smartphone, the Faith seems like a good way to do so.
