Nokia has released an update for its Network+ system app on Lumia Windows Phones. If you're not familiar with what Network+ brings in terms of functionality, the app deals with some cell network settings and is considered pretty important. We've today received a bunch of tips surrounding a 18.104.22.168 release.
Since 1.4, there have been usability improvements related to conditional call forwarding implemented, along with improved call forwarding number selection. In 22.214.171.124 there's now a call counter in the Network+ system area which shows exactly how long you've been active in calls for (system resets defaults the counter back to 0).
