Release a bad movie as an experiment.
Watch nobody buy it because it sucks.
Point and shout "You see? Nobody will buy this stuff without restrictive copyright law!!!!"

Telus and Bell built a JOINT network. It's the same 3G network operating on 850Mhz & 1900Mhz.
Their CDMA Network is on the way out and will not be upgraded.
Rogers also has a 3G network operating on 850Mhz & 1900Mhz.

So, you have the nations three biggest carriers operating on the same frequencies of 850Mhz & 1900Mhz HSPA(+).
The only thing not compatible is the first and second gen networks.

The only carriers that this doesn't affect are Mobilicy and Wind.
a. because they don't have contracts and in case of Wind, will unlock your phone (after 3 months) (not sure about mobilicity)
b. they are on the AWS band and are only compatible with each other. (1700Mhz/2100Mhz)
