I don't know what I'm going to do when Sprint kicks me off of my old Radioshack employee plan. $35/month with taxes for 3000 minutes, 7PM nights, unlimited text messaging, "unlimited" EVDO and a $50/month credit towards anything you can buy from within the phone software, like games and ringtones and Pandora and Loopt.

So that's how we (2 of us) spent most of our $15k summer funds.
