Coworker of mine pointed me to two pages, first is the Rogers iPhone 4 "get me info" page (probably signs you up to all sorts of stuff, but I'm cynical), as well as The Star article saying that the New iPhone to be sold in Canada in 'coming weeks'.
My understanding of the iPhone release was that the US, UK, Germany, France and Japan will get it on release day, June 24, and then 88 other countries, Canada included I'd presume, would get it in "Sept 2010". The article seems to say that us Canadians will get the iPhone 4 at the end of July (possibly coinciding with the end-of-July release of the last version). Fingers crossed we Canucks don't get boned by another month+ of waiting.
