Hello, I have a 1.1.3 8gb iPhone that has recently come under a constant freezing problem. After research on this wonderful website, I've concluded restoring is the best way to go. However, my iPhone has like 40 applications, all with different sets of information I wish not to lose, like car records, bank statements, etc. As well as themes, notes, ringtones, etc. So what I'm asking is, is there any program or process on Windows that one can use to backup for such an event?

On top of that, what's the best method for jailbreaking now-a-days? ZiPhone? And finally, by your professional opinions, is it worth it to go back to 1.1.3 in the end? Or just go 1.1.4?

Thank You for aide in my plethora of questions!
I greatly appreciate it, as I'm sure so does my iPhone!
