I have bought 2 of these phones in the last 2 months. I have the exact same issue with the memory card update package. I am completlyfrustrated with ZTE and Straighttalk for allowing such a messed up phone to be sold with their names on it and charging alot of money. not to mention the countless hrs I have spent reformatting SD card, searching for any online support including SD website, Google, ZTE, straighttalk etc. just to name a few. i have to constantly reenter phone numbers that get erased, apps ive never even had the chance to see. All my money and wasted time because I trusted straight talk for the service when both companies have known about these issues and hAVe done absolutely nothing to redeem themselves. In fact the phones are still on shelves like it doesn't exist. Why?
