I bought an r4i-sdhc on craigslist last night, and it works, but when I go to r4i-sdhc.com and look at the guides on things like installing skins, it shows menus that this r4 does not have. The first screen I see has three buttons, and the website says the far right one is supposed to be settings, but all that button does is open up a menu that lets me do stupid things no one would want to do on an r4, like a ebook reader and a file browser. I suppose it's okay that it works, but I feel like I got ripped off. All the pictures of the r4s on the website have the word Upgrade somewhere on the card, whereas mine does not. This is what mine looks like: http://i.imgur.com/XauLM.jpg Did I get ripped off or something? I can't figure out why things like skins wont work no matter what.
