Hey everyone. Just some advice please as it's my first Apple device and kind of confused! I've had my iPhone 4 for a couple of months and haven't connected it to iTunes to do a backup/add music etc yet. I want to do this and but am worried I'll lose everything I have on my phone at the moment! I have many apps etc and I've heard that when you press sync it over-writes the phone with what's on iTunes (nothing). How can I assure not to lose anything when I connect to iTunes?? Thanks on advance.
