I received a Tango update notice for the Telus LG Optimus 7 on July 17. Haven't applied it yet since the phone was going on a out-of-town trip within hours and I didn't want to take a chance of a last-minute problem arising and the phone not being usable at all.
I won't have access to Zune for a couple of weeks to go back and apply the update, so I won't know exactly what OS and platform updates are going to be applied - but they are available.
One interesting side-note. In the days prior to the update notice, I had gone around the horn with Telus, LG, and Zune (Microsoft) trying to determine how much longer the wait would be to get the Tango update on this phone since it had been declared available back on June 20th. I finally had someone I was talking to in Telus that seemed to be well-connected with knowing the Tango release availability for this phone. Within a day of this person explaining that the update was on a many-week rollout, but also saying that it should now be available for my phone, I suddenly received the notice that the LG Optimus 7 had an update available. Coincidence? Squeaky wheel result? Conspiracy theory? :P
