The Connection Settings app will return shortly on Nokia Collection
Many of you have complained about the absence of the Connection settings application (Network Setup)in Nokia Collection Marketplace some time now. As you well know, in fact, the exclusive Nokia's app was initially removed from the store because it allowed to perform Interop-Unlock on the Lumia devices and subsequently removed again for unknown reasons.
In any case, it would seem that in the Connection Settings will range Lumia Marketplace next week, at least as reported in a post on the Nokia support site:
I can now let you know That A new version of the Network Setup app will be reviewed, to go live this week and it Should Be published worldwide later this week (wk24). Please be aware propagation through Marketplace That may take an additional 3-5 days after the app is published.
The application is extremely useful to quickly configure the network parameters during a new sim card but especially for those who need to send MMS via your Windows Phone device. Obviously we'll let you know quickly if they will again be available to download.
