Well luckily my upgrade isn't available until November 1st. I know Russ posted it can't be done in store, but they said the same thing about the old SERO. Most people have had no problems at all upgrading their SERO phones at BB, myself included. But I will wait and see the luck others have before my upgrade hits
I would love to do it through BB as it is cheaper.
I figure, call customer service, change to SERO premium and then try it at a local BB... may work...may not.
