My wife wants an iPad 2 and as she wants to store her music and TV boxsets on it, she is really going to need a 64Gb as she never wants to delete anything (trust me on this she has also filled our Sky+ HD box in no time lol). To save a bit of money, I was wondering if it was possible to get a 16Gb iPad 2 and then connect an external USB drive to it and watch videos from it? Even if it means jailbreaking it. Is this possible? Better yet, a SD card (in a USB caddy which I already have) .
