Question: how to make eevee evolve into jolteon in pokemon go?
Answer: To evolve your Eevee to a Vaporeon, use the same steps, but name it Rainer instead of Pyro and to evolve your it to a Jolteon, name it Sparky. With the gen-two update, Eevee got two new evolutions. To get a Espeon, rename it Sakura before you evolve your Eevee or rename it Tamao to get an Umbreon.
