Well, I was just at a friends house (he's one of them sup3r 1337 haxzors guys) and I saw his white v1 R4, and in it, an 8 GB SDHC card (and it works). He says he took the SD slot out of a diffrent card and installed it in there. Is this possible? Maybe he put an R4 sticker on a TTDS? i'm very curious about this.
