You can't, as far as I know. You have to trade it from your Pearl, Diamond, or Platinum game, after getting it from your Pokemon Ranger game. Or get it from a friend.
There isn't a Manaphy encounterment in Soul Silver (unless you cheat), but there is a Manaphy egg event for Pokemon Ranger Guardian Signs and you can trade the egg to soul silver from Pokemon Ranger. You can then hatch the egg and it will be a Manaphy and the Manaphy is special because you can breed it to get a Phione. Also there might be a Manaphy event for soul silver coming up sometime later this year (2010). By the way you need to have a Wifi connection set up and you need to connect to wifi to get the Manaphy egg and the Manaphy from the event that may happen.
only if it's traded from a different Pokemon game.
you can't
No, you can not catch Phanpy in SoulSilver. It is a version exclusive to HeartGold.

You can not catch a manaphy on Pokemon diamond. you must trade it somehow on a Pokemon rangers game.
You can't catch bastiodon in Pokemon soulsilver.
A Manaphy is not available in the wild in the Pokemon world. You must trade a Manaphy Egg from Pokemon Ranger.
You cant, but you can look at the book in the Pokemon mansion to see manaphy.
You can't you ave to get someone to give one to you by trading.
You will need a manaphy, unobtainable in soulsilver. Take the manaphy and a ditto to the day care, after some time they will breed, the egg contains... Surprise! Phione!
no
you can't
There is no in-game Phione (or Manaphy) in SS; you must trade it.
catch it? no.
The only legendary eggs you can get in SoulSilver are Phione eggs. You get these by breeding Manaphy at the day-care with a Ditto. You get a weird looking egg which hatches into Phione. Phione doesn't evolve into Manaphy.
you don't, stupid, its a sinnoh Pokemon
