We just got a report that Best Buy’s new line activation system for T-Mobile is down, and apparently has been for almost a week. One of our readers wrote in to let us know he has been trying to purchase a Google Nexus S with a new T-Mobile line of service, but has been unable to due to Best Buy’s activation issue. After repeated calls to store representatives, one admitted that they are not able to activate his Nexus S with a contract, and that he’d have to pay full retail for the device. We’ve pinged Best Buy for comment, but has anyone else had trouble out there trying to buy a Nexus S with new line of service?

Thanks, Nevan!
