No there isn't because now that the quest Unstable Foundations is here, tutorial island is gone.
Tutorial Island no longer exsists (well, it does, but there is no way to get there).
It shouldn't be. The reason Jagex has created the tutorial the way it is currently is because it covers many of the main controls you'd use ingame. It covers combat basics, skill training, how to make money and due to the scattered nature of the starting weapons armor and tools, it makes you go all over runescape to you get to know your way around :) Hope this helps.
There is no way of getting to it, at the moment - it is just there for Scenery.
No. You used to but that was way back in early RuneScape2.
There isn't a better way.
The only way that FunOrb and RuneScape are related is that you can message your friends that are logged on a multiplayer game, and they can send you messages back. Another relationship is that AoG (Armies of Gielinor) is related to RuneScape. In fact, it is based on RuneScape.
The exact same way you got them in the first place.
there is no way you can unless you make another account
It is against Runescape rules to take over accounts that are yours. If your account is stolen however, you should contact Runescape in order to try and get it back instead of hacking it or some other way.
Well if they changed your recovery questions and your password there is no way you can get it back unless they give it back to you, but we both know that's highly unlikely.
Go back the way you came. Or, if you have the Haunted House card from the store, use that and you can exit to the island map -- but either way, you have to work your way back through when you return to the island.
The simplest way of getting to waterbirth island is to talk to Jarvald standing on the west most dock in Rellekka. If you have not completed the quest "The Fremennik Trials" you will also need 1k for travel.
