FYI, I see that the 1314 firmware update for the Lumia 920 is now live, check your settings for the update. only took about ~15min to download, install and migrate settings and back to my homescreen.

haven't found a changelog for this from Rogers but should be the same as AT&T?
Since I just installed it and havent had time to test it much as this is not my primary phone, but wanted to share with the WP community here. Hopefully it fixes the signal and connectivity issues others have had, and brings other improvements as noted from the AT&T release.
I've used the Lumia 920 phone for ~3 months then switched back to my iphone 4s for the past month... with this update I will give the 920 another chance.. I do love the screen, camera, keyboard and some other featues but WP8 still needs alot of work, not just in the OS but quality of apps that are allowed into the windows app store.
So so far, my phone has not gotten inexplicably hot and stopped randomly draining the battery. Back to the normal issues of Rogers not having enough coverage where I work/live but at least my phone is not creating its own heat death because of it any more. 🙂
