This doesn’t sound like good news for folks out there who are planning to pick up a Nexus S. Reports are filtering in that Best Buy’s new line activation system for T-Mobile is down, and it has apparently been in that state for a week. Readers have reported being unable to purchase the phone with a new T-Mobile line due to the outage and thus had to pay full retail for the device. Not exactly a good solution for the customer and also T-Mobile. Have you experienced such issues with purchasing a Nexus S? Let us know via the comments section.
