Same here, haven't gotten my update from Rogers yet...eagerly waiting as each day passes by
I was able to get my phone to update using the "trick" that gets you to:
1) turn off WiFi and cell data in the phone
2) plug the phone into the PC using USB
3) open Zune if it did not auto load.
4) click on update and 2 or 3 seconds after you click update either unplug your Ethernet cable or disable your connection.
5) Zune will detect an update 8112 most likely.
6) reconnect your internet or enable it
7) click update now and wait for the first update to finish.
8) repeat steps 4-7 and you will get update tango update.
It does work but timing is everything. If tour too fast to drop your connection you will get an error and if ur too slow you will get the "your phone is up to date" msg. But it does work. Just remember to re-enable your data on the phone after the update so everything works. Hope this helps.
