I have recently bought a Huawei E585 wireless modem to use with my wifi ipad2. I have put a 32gb memory card in the mifi and copied a few movies onto it from my Mac. How do I now play those movies on my iPad? *I have logged into the 3 website which shows data usage etc & can see the movie files that I have put on the memory card - but when I select one it will not upload or play on my iPad. What am I doing wrong?...
