I am changing over to 3 from Orange. I now have my PAC code and instructions how to unlock my phone (Sony Xperia Z2) - currently working out my notice. Apart from transferring all of my photos and videos over to my computer, is there a better way of doing this - somebody mentioned Cloud a while ago, but don't know how to use it or know anything about it? I do not have a memory card for my phone. I just want to make sure that my photos don't disappear during the transfer and also need to free up some space on my phone. Thank you.
