Here is an interesting turn of events. First we got lots of rumors LG will be once again manufacturing the next Google smartphone - the Nexus 5. Then we get to see the LG D820 leaking through the FCC (http://www.gsmarena.com/lg_d820_certified_by_the_fcc_might_be_the_nexus_5-news-6737.php), so many people decided this is indeed the Nexus 5.
Unfortunately, the usually very reliable
evleaks tweeted (http://www.gsmarena.com/lg_d820_is_cdma_g2_model_not_the_nexus_5-news-6749.php) the LG D820 is in fact just the CDMA version of the LG G2 (http://www.gsmarena.com/lg_g2-5543.php) falgship, not the next Nexus device.
Well, today
evleaks has retracted his previous statement, saying that it looks like he was wrong.
Happy to say it looks like I was wrong about the LG D820/D821...
