AT&T has settled a long-running class action lawsuit filed against it for failing to provide unlock codes for its handset lineup between March 12, 1999 and April 2, 2010 which covers all handsets offered by the carrier with the lone exception being the iPhone. While the settlement will not provide for financial compensation, it is supposed to provide unlock codes for customers that meet the following criteria:
Customers with postpaid accounts who have completed a minimum of 90 days of active service and are in good standing and those with prepaid accounts who have a receipt or other proof of purchase of the handset. Those who own handsets for which AT&T has an exclusive period of less than 10 months (which would exclude the iPhone) will have to wait until the 10-month period expires before an unlock code can be received.
In order to opt out of the settlement or object to it, June 4, 2010 is the postmark date for filing. The final approval hearing will be held on July 2, 2010 with more details found here.
