Canadians with a serious need for speed might want to pack their bags and move to one of Canada’s five largest cities — Vancouver, Calgary, Toronto, Ottawa and Montreal — as today Rogers announced that its 21Mbps HSPA+ network upgrade has gone live and is ripe for the picking. Almost. No current Rogers handsets are capable of reaching such speeds, but if mobile internet is something you’re absolutely smitten with then you should definitely consider pre-ordering the new 21Mbps HSPA+ Mobile Internet Rocket Stick. It starts off at $79.99 on contract (which is $79.99 more than Rogers’ current Rocket Stick offerings), but c’mon; not owning the latest and greatest gear flies straight in the face of what we here at BGR are all about. As for the general benefits for current 3G handset owners, the upgrade also comes with an overhaul of the network’s backend, meaning more people should be able to simultaneously use data without making the network come to a screeching halt.
