We find this to be a little sad, but it says a lot about a carrier's commitment to software updates when a dicontinued product gets the download before their portfolio of devices. WPCentral has kept a close eye on the Tango update situation and they've pointed out a few oddities that we just alluded to.
First up is word that AT&T actually already has the Tango update ready...they're just not rolling it out. It's not clear why, but a few Samsung Focus S users noticed they received the update normally while others performed the disconnect trick to force the update to their phone. Browsing through the article's many comments it appears most Focus S, Focus Flash and even one LG Quantum owner have forced the update successfully. We just tried it with our Focus 1 (rev 1.3), but after multiple attempts we weren't so lucky.
To try this for yourself put your device in Airplane Mode, connect your phone to your computer, go to Settings > Update, and as Zune shows a loading bar disconnect your internet connection after a few seconds. Wait to see if it worked and if it did, Zune will tell you an update is available and you can reconnect your internet.
Meanwhile, there was also the surprising news that the discontinued Dell Venue Pro has actually begun to receive its Tango update. That comes a big surprise as many probably expected support for the device to evaporate, but sure enough WPCentral received the update without any of the above trickery required. Finally in a related note, several Rogers customers have let us know they've begun receiving updates for their Windows Phones. That ranges from the Focus 1 to the LG Quantum even up to the Nokia Lumia 900.
We can imagine how frustrated users must feel with the carriers (we are too) since the Tango update has technically gone live already for the globe. When users have to resort to shady methods just to get a promised update (and to solve that godawful keyboard bug) you know something, somewhere is broken.
