Agreed just call them. With Rogers you just never know.
As an example, I got bored and checked through Rogers online and under wireless it asked if I wanted to upgrade to the 3GS. My cell plan is only 92 a month and then is discounted further because, well, Rogers screws up... A LOT!
I clicked the upgrade option just to see what it would cost and it gave me the $199/$299 options. Only thing I can see is that because my cable and internet are all under my wireless bill now I somehow qualified that way. Now I just have to get rid of this darned 3G
