I have an iPhone 4. And yesterday, my sister was checking all my personal stuff and I was annoyed so I decided to set a password. I just typed really fast and I forgot to look at my phone. It was up supposed to be 1845 but I think I typed too fast, twice. And when I tried to open it, it said wrong password. I tried again and again and now it says, "iPhone is disabled connect to iTunes" my phone is jailbroken and I have lots of important contacts, photos, apps, and stuff like that. And I don't know what to do. And do we need to download a backup for it? Or is there any other way? My friend told me to take the SIM card out to restore it. But I don't think it will work. Help?
Added (1). It's ios4.1. I don't have my own apple ID and my laptop had to be repaired the other day and I can't resume all my apps.
Added (2). *resync. Will my jailbroken apps disappear? I also downloaded a few apps with my dads account. I'm stupid
