Sprint Built in wireless

SO I'm looking into getting a new Inspirion, and I'm interested in getting the Sprint inbuilt wireless card, but when I asked Sprint what plan prices were (on their website they only have actual cards and Phone As Modem options) they tell me that those are the only options and they don't have any inuilt cards, yet Dell is obviously offering it, so does anyone know what the deal is? Sprint told me to contact Dell, but all I can find is "Contact Sprint for plan details". I'd like to just send an email to Dell,  but there's no option to do that through the site so I thought I'd try this. I just want to know what plan rates are, and if they're the same as they're regual data plans or what...even info on Verizon would be helpful, since dealing with Sprint is begining to be a hassel, even though I'm a 'valued customer'. If anyone can offer help, it would greatly appreciated!!
