Rollouts of the upgrade to Windows 10 Mobile for Windows Phone 8.1 devices kicked off on Wednesday, January 13th in Poland via T-Mobile; and around the world other carriers have also started to upgrade customers' devices to Microsoft's latest offering on Mobile.
Now, it appears that users residing in countries across Latin America have reported that they are receiving the update, with one user showing off Windows 10 Mobile build 10586.29.
