You can use Wifi on a DSI, if it doesn't work with you then it's probably because you have WPA connection security settings. WPA connection will allow you to surf the internet and go on the DSI Shop etc., but will not allow you to play games over Nintendo Wifi Connection. To do this, you will have to change your settings to WEP so that you can play on Wifi on your DSI. However, WEP is not as safe to use an internet connection as WPA, so be careful. Hope I Helped...

you cant
Every single ds, ds lite, dsi, and dsi XL comes with built in wifi. To get to it, you have to have a wifi compatible game, and there will be wifi settings somehwhere on the game. You have to edit the settings. But i cant help you there. :)
You can get facebook on DSI. You just need wifi then when u have wifi you go on DSI shop go on this box that says FREE and then you will find internet
the dsi game has to have a wi-fi option (gts on Pokemon for example) and even thin it is restricted to what ever the game has on it so you cant just go to sites like this on your dsi.
yes, you can
it needs some sort of wifi connection to a wireless router
No. A DSI cant use a 3DS charger.
both are wifi.
Yes, the Nintendo DSi XL has WiFi and can connect to the internet.
Indeed-- If you have WiFi with a DSi you can go on the internet.
You must be in a free-wifi zone, even using DSi/DSi XL you cannot use locked wi-fi point or a Payible one - only Free-wifi zones maybe used
You have to own wifi
