Nokia promised two updates coming to the Nokia Lumia 800; one that would enable the full 1450mAh capacity of the battery, instead of the 1300mAh it currently uses, and a second one providing full offline navigation on Nokia Drive. Unfortunately, this update doesn’t seem to be neither of those. I just plugged my Nokia Lumia 800 to my Mac and I was notified there was an update available; seems like it’s a fix for a Microsoft Exchange Server 2003 issue. I’ll keep you notified if I find anything new. To update just plug your 800 to the Mac Connector or Zune in your Windows PC. Don’t pull the plug early!
