Activating a Unlocked iPhone with Koodo Prepaid

Sorry! I just noticed the "Change SIM Card" option under my Self Serve options online. It says to...Yup.

Is it possible to buy a used unlocked iPhone and use it with Koodo prepaid? ->Yes. Do all iPhone models work with Koodo prepaid? I would ideally like to get an iPhone 4s or higher. ->Any iphone 3GS or newer will work with Koodo. Can I buy a used Koodo iPhone that is locked to Koodo postpaid and activate it on prepaid? Or does it have to be an unlocked iPhone? ->Any koodo phone with a sim card can be used either on Koodo prepaid or Koodo postpaid. iPhones locked to Telus will work as well. I am already with Koodo prepaid, and my phone takes a regular sized SIM card. Can I just transfer my account to a micro SIM card that fits in the iPhone? How? Is it possible to do this without a phone, or would I have to have the iPhone with me already to activate my account on the new micro SIM card? ->Yes. Just buy the new sim and swap it onto your existing account. You should be able to do this through self serve.
