AT&T Cingular is offering today online the Sony Ericsson J220a Refurbished GoPhone for only $9.99, including free overnight shipping. This can be purchased with either GoPhone plan (Pick your Plan or Pay as You Go), so no airtime purchase is required.
The J220a at $10 is the lowest price so far for the phone at-retail, and it is the lowest price Cingular has ever offered for a GoPhone for new customers without contract.
