So today, I was downloading a 40 mb application, and I had 500 mb free. Yet it told me "Insufficient storage available". Well I bought an SD card, hoping it would fix the issue (I was meaning to buy one regardless). Well, it didn't work, and I can't download anything. Please speak english I don't know what rooting is or how to do much on the smart phone, I've had it for a month, and whenever I get a problem (which is too often, by the way...) it's hard to follow peoples advice. Thanks.
