I would def recommend using the Switch device wizard in device manager.. Will move all your content and contacts while also updating BBM contacts with your new pin. All seamless and simple.
Funny this thread got started because I'm in the same position today. I've been patient with my Telus Storm, have done updates and still go through issues. It's too bad since it's a nice phone but I think the Tour will be a better device for me. Too bad Best Buy doesn't have any stock since I have their exchange plan for easy exchange.
I just got a tour last night and used the DM to tranfer all my stuff and it well hassle free. its a learning curve cuz you always want to press the screen but so far, I love the Tour!
