First off, a combination of web discounts and a mail in rebate bring the CricKet EZ pphone down to a mere $30. Though I wouldn't get it; it had 911 issues in the past and seems to generally be a very, very low-end phone.
Second, CricKet has, through mail-in rebates and web discounts, slashed prices on their mobile broadband options. Not the plans, just the phones. The USB modem is now $59 after rebates and discounts, and the PC card (which will get phased out relatively soon due to incompatibilities with the newer parts of CricKet's network) is, after rebates, free. This is with no contract, though in order to get the rebate you have to stay with CricKet for a few months.
