The Nintendo 3DS will be able to play Nintendo DS and DSi games but games published for the Nintendo 3DS will not be compatible with those systems.
No, there is no way to do so. The 3DS will support Miis, though.
You don't. The DS Lite doesn't have an SD slot; only the DSi does (including DSi XL.)
What you do is just go in your album and there is a sticker bar and put the star on your favorite pic. Then you go to your dsi menu and walla there it is. I know this because I have a dsi of my own. Enjoy;)
Yes and no. It is safe to put stickers on your DSi because it has the ability for stuff to stick to it and will cause no problem if you put the sticker on it. It is not safe because, generally, the stickers will not come off. Just be sure that it is your choice to put them on there, and if you want to put them on there, make sure you want it to be there forever.
no
you can put a phone charm on every phone in the world
The Nintendo DSi has a built-in web browser.
I put a phone charm on the antenna since this phone doesn't have a phone charm place.
I do not know but i do know that you can put an SD card to put songs on the DSi.
Unfortunately no. You can only put music on a Nintendo DSi and N3DS with a SanDisk.
Yes, if you have a SDcard.
yes
YES
The photos are put on your Facebook profile, in an album called "Photos from Nintendo DSi."
Only in the original Nintendo DS and the Nintendo DS Lite. DSi, DSi XL and 3DS do not have a slot to put GBA games into.
I am not familiar in whether or not the phone has a phone charm hole but if it does not you can always buy a self-adhesive phone charm o-ring and put it on that way :)
