Im switching from Fido to Rogers on my prepaid cell phone. I have an iPhone 3gs right now. I am planning to get an iPhone 4 later, so I asked for a multiformat card so I can use the whole sim card now for the iPhone 3gs and when I get my iPhone 4 I can just pop it out of the border and put it in. The person at Rogers said they recommend not to do that. I asked why and she said she didn't know. She asked everyone else at the store and still nobody knew. Why can't I do that?
Thanks
