Can I buy an iPhone and pay for it monthly?

My current phone is dying.Am I able to purchase an iPhone (thinking the 4 or 4S) and pay for it monthly instead of putting down all the money at once? I'm not talking about the monthly payment a phone require anyway, but the actual purchasing of the phone - I would rather do small payments versus putting forward all that money at one time. This would be with Rogers.

It depends if your contract is up or in renewal. If it is up you're able to "upgrade" your device, and if not, they may pay half the price you pay the other half. But if you have only had the phone a few months, on contract and it is dying, chances are you're unable to upgrade. You could try on places like KIJIJI.
