Bad news if you're on Vodafone and were yearning for that Windows Phone 7 Tango refresh. The update was originally due in July but that time has since come and gone with no update. Now Vodafone has confirmed in a blog post that Tango has been canceled:
"Roll out of this update has been canceled. We have now been advised that this update will not be rolling out to Vodafone customers globally. This is due to a critical WiFi issue identified during testing in an overseas market. We expect the fix for this issue to be included in a future update but do not have any information on delivery timeframes."
The good news is it sounds like whatever issue there is with WiFi in Tango will be addressed for the planned 7.8 update, which Vodafone will most likely roll out. On the other hand that update still months away for current users.
