You can't currently get flint in Minecraft PE.
Yes it does.
You would have to make a Creative Mode world...
you cant at least not yet as at the moment you cant craft in the pocket addition.
as of 0.6.0, it is currently impossible to acquire a "flint and steel" in creative mode. this is most likely due to the low processing power ram capacity of today's mobile phones. however, there are some mobile mods that somehow bypass mojang's efforts and allow the use of flint and steel in creative. did i sound smart? keep in mind that i am not smart and that this is just practice for my report next month.
In PE you can't craft anything.
Currently, you cannot change day to night but it is thought to come in a few updates.
There is no app you download to change your current gamemode in a world in Minecraft: Pocket Edition. Once you select a gamemode for a world, that is your permanent mode, you can't change it around.
make a bucket out of wooden planks.
No, nor can you in survival. The Nether Reactor of Minecraft PE is not the same as the Nether in the PC or Xbox versions. Nether reactors only work in survival (intentional)
Survival and creative single and multiplayer
