Word coming in from BGR is that Best Buy is currently experiencing troubles activating new T-Mobile lines. According to BGR, Best Buy’s new line activation system for T-Mobile has been down for almost a week. Because of this, if you want to purchase a Nexus S (or other T-Mobile handsets), you will be forced to pay the full retail price (that is, if you really really want it that badly). We’re unsure whether this is a nationwide issue or limited to certain areas. Best Buy has yet to comment on the issues. For those that have tried to purchase a Nexus S or any other T-Mobile handset with new service at Best Buy, have you experienced any troubles? Let us know in the comments!
