Hello everyone! I just got myself a PS VITA original model. I plan on hacking it, but my main question is I have seen a mod where you can get an SD card reader for the 3G model and use that instead. How does this work, and will it work like regular storage would? I am new to the vita, and wanted to know if I should bother buying the expensive memory card, or if I can just use the SD card for everything? Wanted to use a 400GB card ideally.
