Rogers Wireless, Apple’s exclusive iPhone retailer in Canada, has announced that September quarter sales of the touchscreen handset totaled more than a quarter million units, boosting both its subscriber count and average user revenue by a large margin.

Rogers’ iPhone deal is expected to have a significant impact on rivals, none of which run GSM-based networks compatible with the iPhone. The carrier said about a third of its customers are either converting from a competing provider or are new to cellphone service. This is a huge competitive advantage in that region, needless to say.

Analysts expect Bell Canada, the 3rd place wireless competitor in the area, are expected to lose 35-40% of their user base to Rogers when they release their economic reports later this week.
