Where can you evolve Eevee in soul sliver?

Answer 1

If you mean how to make it evolve: In SoulSilver and HeartGold, you can get an Espeon by training your Eevee in the day time, and at a certain lvl. it will evolve into Espeon. To get Umbreon, you do the same thing, except you train it at night (it may take a couple tries when it's going to evolve to get it to evolve into Umbreon if you've trained it in the day time, too). To get Jolteon, use a thunder stone. Flareon, fire stone. Vaporeon, water stone. To get Leafeon and Glaceon, trade to Diamond, Pearl, or Platinum, and for Leafeon, go to the forest after the 'Flower Town' and make it go up a lvl. and it should evolve into Leafeon. For Glaceon, go to the snowy rout, and make it go up a lvl. and you get a Glaceon. Then trade back to get it in HeartGold/SoulSilver.
