Nope, Bell/Telus havent introduced better plans. However I have heard that Telus/Bell have allowed customers to keep their voice plans, and SOME people have been able to keep their data (sometimes unlimited) with Bell, so that's an upside to some people who are already with Bell/Telus.
It's just aweful that all three require a THREE year contract for a freaking phone, or even an iPhone!!! The Canadian cellphone industry is aweful. Everyone is hoping Wind Mobile will change that, but due to CRTC criticism, Wind won't be launching anytime soon now. Ugh.
