I noticed that iOS 4.1 software is available and I really want to download it but I am afraid. I am afraid that everything will get deleted like what happened last time. I have found a program that copies my music, videos and photos so I can use that as my media backup. But how about the notes and contacts? I have many information there and I don't want them to get deleted especially the notes. Will updating the software delete my contacts and notes? I know that it will delete media but how about the contacts and notes? Those are very important for me. And also, what do backups save? Do they save contacts and notes? Please give me answers that you have actually tried and worked. oh, and, is Address book same as Contacts?
