Need advice on Sim cards...

[Special K]

Where can I get a sim card for an iPhone 3GS in downtown Montreal and what would the cost be? Once I purchase the sim card can I then just add minutes and internet on it and where would I go to charge the sim card?

Any info would be appreciated.

Thanks JSB and Rev. The Petro sounds like a feasible option. I'll check it out.
