T-Mobile customers can go to the T-Mobile Tuesdays seection in the T Life app, and save the offer for a free pair of eclipse glasses. You can then take your phone to your local T-Mobile or Metro by T-Mobile store and present your app to claim the glasses. Then, come April 8, stare. Stare into the eclipse like you're Larry David inspecting a conversation partner for evidence of dishonesty. (Bonus points if you then break the stare, saying "Okay. Okay.") Shop Now at T-Mobile
