You cannot redo the mission for another Manaphy egg; the mission is a one time completion only. Even restarting the game won't reset the mission.

There is no trainer in Pokemon Platinum with a Manaphy. However, you can trade with someone who has a Manaphy, or complete the special Ranger mission in Pokemon Ranger and transfer the Manaphy egg over to Pokemon Diamond, Pearl, or Platinum.
the egg hatches manaphy since manaphy and phione are different pokemon. it takes about 5000-10000 steps
to get phione you simply get manaphy from Pokemon ranger (the old version) and put it in day care with a ditto they will have a egg & that egg is a phione egg!!
i am not sure but probably so the only ones that do not are the legendary and starter except for manaphy who's egg is another Pokemon
No offenese, but if you want a Manaphy, you have to getPokemon Rangers, Shadows of Alma and complete theRetrive The Manaphy Egg. Then read the instructions bookto see how to get Manaphy Egg on Pearl.
