Saving new contacts to the sim card

I would like to know with the Android OS if you can save your new contacts to the SIM card besides in the phone memory? Just like any other normal cell phones whereby you have an option to save your new contacts in the phone memory, SIM card or both.
Also with the Android OS, can you bluetooth photos, movie clips, movies, notes, songs & so forth to other phones using different OS like Symbian or Winmo?
The biggest failing of the iphone is that you are unable to do that. New contacts are saved in the phone memory only.
Another weakness of the iphone is that you cannot bluetooth anything to another phone using different OS. For that matter if I am not mistaken, you cannot bluetooth to another iphone as well.
I would like to migrate to Android as it looks like a very promising OS.
Iphone apps are cheap & quite good in general but can't say the same about the phone when it comes to functionality.
I have used a lot of Symbian OS phones in the past.
Good OS but their apps are far too expensive.
Thank you & looking forward to all your replies soon.
