We've received a tip that the New Zealand mobile operator Telecom is currently rolling out a firmware update for the Nokia Lumia 920. It's believed the update unlocks 4G connectivity, which was previously disabled. The network will be launching its 4G upgrade next month and this update will ensure Lumia 920 owners will be able to enjoy faster data transfer speeds.
It's good to see the mobile operator roll out Windows Phone upgrades prior to launching 4G. Let us know if you've also received the firmware update in the comments.
Thanks, brucexli, for the tip!
