I am utilizing Sony Ericsson xperia x10 from final few months. It wasfunctioning rather well. I was met with this phone. Then I heard thepublish of edition android 2.1. I updated the novel edition in mycell phone. afterwards updating my phone to this novel edition, myphone commenced inducing some troubles. So I thought to acquire ridof this edition and set up 1.6, but I am not capable to do it.
