Add line for the purpose of getting discounted iphone?

[apalmer]

Recently my iphone 4 was stolen, and of course i bought it under a 2-year contract agreement. Right now i am using my old 2g iphone that is just about to fall apart in its place. I was wondering however, if i did an add line (still will be only me using the service) and received the newer iphone 4 for a discounted price would i be able to reduce the old iphones line to a no data plan/no sms line by using an old non-smartphone in its place(swap sim)? SO basically my goal here is to pay only $9.99 more every month in order to buy an iphone 4 at the discount price. Will that work? Any reasons to think of that might cause this to backfire?

Thanks in advance for any input.

Yes, if you're not using an iphone on the other line then you dont need to keep an iphone data plan or texts.
You'll just let it it sit there without using just to get the $199 iphone price right?
