I am currently have a iphone 4 still running on 5.1.1 and i want to update to the lastest ios firmware 6.0.1 but the problem is that the laptop i been syncing and backup my music contracts and stuff broke. So i am wondering is there a way i can update my phone to the new firmware. I tried using over the air and it wouldn't work. My mom has a laptop but she uses her iphone 4 on that laptop to sync her stuff. If i sync my phone and update it on her laptop will i loose everything in my phone including contacts and music, photos also? And wondering if there is a why itunes and save your music on your phone to the computer since i dont wanna lose them.
Thanks
