Rogers customers will be very aware that to get an iPhone 4 at discounted price, you need to sign a 3-year contract AND have a data plan attached to that contract.
Telus customers will be happy to hear that you no longer have to sign up for a data plan to get the iPhone 4 at a discounted price.
Why would someone want an iPhone without a data plan? Perhaps you want to keep it old school and use your phone as a phone, and do the rest of your computing on a computer. Free WiFi connections are available all over the city as well.
Just remember: the iPhone does a lot of data pulling for its various apps, make sure to disable cellular data on your iPhone if you don’t have a data plan. Failure to do so can result in a large cellphone bill.
