Good news came late today for all those Lumia 900 owners out there. It appears that Nokia has officially released the software update to resolve the handset's data connectivity issues -- a full three days early, in fact. Users may download the software through either Zune on the PC or Windows Phone 7 Connector on the Mac. For those who'd prefer to swap out their handset at an AT&T store, you have between now and April 21st to complete the exchange.DevelopingNokia Lumia 900 data connectivity fix
