I'm buying a second-hand iPhone 4 from a girl I know. It is locked to Fido and I just had some questions regarding their pay-as-you-go options.

What kinds of plans do they offer for this? Are they expensive? I tried going on the website to ask them questions, but apparently I can only do that if I have an account with them. I'd call them, but I don't have a phone (which is why I'm buying the iPhone).

So if I wanted a plan for unlimited incoming calls, data, unlimited text messaging, free calling after a certain time, etc, how much would that approximately cost? I don't want to buy this phone without knowing all I need to before I spend a lot of money on this phone.
