Bell could land a victory against other Canadian carriers by offering a strong promo deal for smartphones and the iPad, a leaked memo shows. Similar to the deals Rogers has been running since 2008, the carrier would provide 6GB of data for $30 per month for BlackBerries, iPhones and other smartphones, including tethering. The deal identified by BGR would start July 30 -- the same day the iPhone 4 is available in Canada -- and would run until September 30, the end of the summer quarter.
