You might find it at Nino store. Keep in mind all current flash cards for 3DS can only play DS games. Gateway 3DS will be released end of june, supposedly the first 3DS flash card that can load 3DS roms.
Yes, I intend to play DS games only on it.

I have a couple of questions also.

1- While playing DS games, do I have access to the internet?
2- Can I play DS games online using R4i? Like Pokemon?
3- Someone told my brother that if I used R4i once, I won't be able to access the internet on the console at all, is it true?
4- If I used the R4i card and played DS games, will I be able to play 3DS games online again?
5- Can I play online if I get original DS cards?

Only thing I know is that you better NOT update your firmware if you use a flash card. Updates can render flash cards unusable. If no one can answer your questions here, I suggest you ask at gbatemp.net.
There are many fakes in Lebanon, they probably work but apparently they can damage your DS. So, be careful when buying the product.
That is why I'm asking for a trusted place that sells them.
i bought one from saudi a few years ago, but i bought for the original nintendo ds back then so I don't know if it supports 3dses
i know a place that sells them, you can access the internet but if you update your device then the card wont work and you have to find an updated hack for it to work (its the software in the memory card that goes into the R4)
pm me about the stores location
