Flareon NAME your Eevee "Pyro" Jolteon NAME your Eevee "Sparky" Vaporeon NAME your Eevee "Rainer" From the original reddit source www.reddit.com/r/pokemongo/comments/4t0cpo/psa_how_to_force_your_eevee_to_evolve_into_your/ "Hey All, It would seem that there is in fact a way to force an evolution of your Eevee. The Eevee Brothers from the original anime were named Rainer, Pyro, Sparky and they owned a Vaporeon, Flareon and Jolteon respectively. If you nickname your Eevee either Rainer, Pyro or Sparky, your Eevee will evolve into that desired Eeveelution! Sparky = Jolteon Rainer = Vaporeon Pyro = Flareon I have tried it on a few Eevees and so have friends, and we've seen a 100% success rate. Feel free to give it a try and post back here with results!"
