Update: Brightspot is official.
Already confused by the myriad of prepaid carriers out there? Well, Target thinks there should be one more. After @evleaks outed the name and pricing last night, more details have emerged. Target's prepaid service will run on the T-Mobile network and is launching October 6th online and in Target stores.
Pricing starts at $35 per month for unlimited talk and text, but no mobile data. For $50 you get "unlimited" data, including 1GB of 4G.
