No Telus branding, not even Telus Navigator installed (though it can be according to the site). Not even a logo on the default wallpaper as some of the pictures on their site show. Only spot I've seen Telus so far is in the SIMTools app due to it being their SIM card.
Speed-wise so far I'm liking it, haven't installed too much though. The on-screen qwerty is nice, the physical one though I'm agreeing with all those who said the buttons are too small, they are if you're like me and have big fingers.
I bought it on Telus contract.
As for quantities, the store I got it at (in NW Calgary) had about 20 that arrived today, though 3 of them walked out the door within 30 minutes of them arriving in store so I'd say supplies may be up and down a bit depending on location. Another store I talked to yesterday had ordered about 20 as well, but they did have a sizable list of people who had expressed interest (they didn't do pre-orders, more just a 'put your name on the list and we'll call to let you know its available' type thing)
