The current Sony Ericsson Cedar release date is not official but we can expect Sony to launch the Cedar by the third quarter of this year (2010). The Sony Ericsson Cedar is actually also known as the Sony Ericsson Cedar GreenHeart depending on where you live. It is a GSM cell phone and can therefore be unlocked, which we will probably post a guide on how to do soon. At the time of writing, this smartphone is just known as “coming soon” but we will update this article with any new Sony Ericsson Cedar information or details. Stay tuned!
