Lesson learned...

Received my cellphone bill and was shocked to see that I had been charged $90 for data roaming charges while in the US! Yikes! Called Rogers up, talked to a nice guy named Dylan and he gladly charged me half of the roaming charges. Phew! Total bill is now $93 instead of $138. Still twice my normal cellphone bill but better than $138. Lesson learned. Turn off 3G when in the States!!!
