mobile broadband question

[digitalreflex]

I have a question about the t-mobile prepaid broadband. I got my phone working on it prepaid but can't figure out how to add the $30 300mb mobile broadband package (listed on their page). Only thing I can seem to add is the $1.49 30mb daily pass. Is there a specific phone I need to have on the my t-mobile site to get that? Sorry if the answer is on this site, I tried google but got nowhere.

I think that plan is only for broadband devices like netbooks and tablets.

I would love to have that plan for my iPhone.
