Thats the million dollar question is who of the big 3 end up with it. I have a feeling it will be Rogers since both Bell and Telus have the SGS2 and Rogers currently doesn't. If Telus doesn't get it I guess I will be defaulting to the Iphone since Telus' SGS2 blows.
What does it matter
"who's getting it"? It's an unlocked phone.
When the Nexus S came out I went to Best Buy Mobile picked up the "Koodo" Nexus S (Not that it mattered they were all sim-unlocked loaded with stock android) because it was $425 and everyone else's was oddly more expensive. I even joked with the Best Buy guy at the time
"Is anyone even buying the $550/600 Rogers/Bell Nexus S?", "No, not really" he laughed.
I didn't even end up going with Koodo, I just swapped out my sim from my old device, popped it into my new Nexus S and I was off to the races.
For so long as the Galaxy Nexus
IS available in Canada, (which of course it will be), just pick one up and go shopping around for your preferred plan/service provider. As I understand it, the Galaxy Nexus will be a Pentaband phone including the Band IV AWS frequencies so it will be compatible with AT&T/T-Mobile/Bell/Telus/Rogers/Wind/Moblicity/Public Mob/Videotron and all the sub-brands.
Technically, even if it isn't immediately available in Canada just order the AT&T (i.e. NOT Verizon) version from Amazon and pop in a RoBellUs/Wind/Moblicity/PubMob/Vidtron sim-card and you're good to go.
In truth, I suppose if you were hell bent on the
"I want to buy the phone for a nickel and sign up for a 12yr contract" suicide way of shopping then yes, who's offering it will matter.
***Small Addition***
As per the Hong Kong Launch, the LTE version of the Galaxy Nexus will be for Verizon's quirky CDMA/LTE network implementation (
Think HTC Thunderbolt's CDMA/LTE compatibility, not HSPA+/LTE). That having been said the LTE Galaxy Nexus won't work on anyone's but Verizon's network or another provider that has the same oddball implementation as them.
