I'm waiting for a reply to this also. I downloaded the linked browser & installed it as instructed. (Same one I had been using apparently). I signed in a day ago & still no sync has occurred, plus my old bookmarks are lost from my online account it seems.
I've been using Blackberry & Opera for years. I just reorganized all my bookmarks & found Opera link no longer works. My 9310 smartphone is my constant companion & main access to the web. Opera has made this possible with its excellent Mini browser.
