Yes, it appears that Rogers’ $159 16GB / $269 32GB trend has spilled over to the other carriers, and this will be a Canadian mosquito-swatting competition to see which carrier can be lure you into the light.

What’s lovely about this is that all three carriers are being more lax about their hardware upgrade requirements, so even if you’ve upgraded your phone quite recently, you can probably eek out a lower-cost iPhone 4 than you would any other device.

This is the first time that the iPhone has launched simultaneously on Canadians networks. If you recall, Telus and Bell only launched their HSPA+ network in November 2009, so up until then Rogers had exclusive sale opportunities for the iPhone 3GS. Hence, this time, why the competition is so heated.

As well, Bell is offering a 6GB/$30 monthly data plan, which jibes with Rogers’ latest offering, too. Get this while it’s hot, as it will probably expire September 30th. Telus will likely have to follow suit, though no announcements have been made.

Bell is also offering a $10/month iPad sharing offer, so if you sign up for that 6GB plan, you can share it with your iPad for only $10. Not bad. Rogers is offering the same ability, but for $20/month.
