Last night I was able to push the 7.8 update to my Nokia Lumia 710 through Zune. Upon trying to get internet sharing to work, or any of the new Nokia apps, I was told that I dont have the right OS version, although I've upgraded to 8862. My firmware is still stuck down at 1600.3013.8107.11502. I think its worth noting that I recieve my Lumia 710 directly from Microsoft, so I think that it's an older version that hadn't been shipped with any updates at all.
All I really want is internet sharing, but even though that firmware update came out like a year ago, I still don't have it. Zune tells me that my software is up to date, but my phone tells me otherwise. And yes, I have checked what updates are available for Canada, for my provider and my network carries the latest update.
I'd contact a Nokia Care Point on receiving the 7.8 firmware for your phone. Alternatively you may want to contact Nokia through twitter using @nokiahelps on this.
