I was looking at rogers flyers and website and noticed that cheapest payg  
phones are less than cheapest no term and if you compare payg with normal it  
says n/a for all payg prices.  So is there a catch here?  Can you buy a payg  
and use it with a rogers sim and plan?  Are there more charges for payg?  Or  
are rogers phones locked against rogers phones?
