What will happen if I use itunes with a jail broken Iphone?

I have an Iphone 3s which was recently jail broken via a system called cydia in China. I haven't clicked on the cydia app yet i only jail broke it so i can put my Australian sim card in it. When i connected my iphone with itunes it attempted to 'restore' but i unplugged it. So what will happen to my phone if I connect it to itunes? Will it corrupt it? Full details please!
btw i paid for some guy to jail break my phone so i have no idea about cydia

Here's the bottom line: You should only jailbreak your phone if you know what you are doing or if you have a friend that will always be there to help you. If you really need a jailbroken iPhone for some reason, what i would suggest is to learn all about it and learn how to do it yourself (some google searches on jailbreaking will do the trick).

Before i can go into details about your specific situation, i need some more details: What version iPhone do you have? What version of iOS is installed? Is your iPhone working properly when it is not hooked up to your computer?

In any case, you should be totally fine hooking your iPhone up to iTunes to sync, manage music, videos, photos, or anything else.

iTunes should not automatically restore your iPhone, jailbroken or not, but you might have accidentally clicked the "Restore" or "Update Firmware" button.

When you get this answer please respond or update your question so i can help you better.

  • My jail broken iphone won't work? So a few days ago I downloaded envasi0n & jail broke my iphone 4.It worked for the first day or 2 then it crashed & it kept saying exit to safe mode. I was finally out of safe mode but the jailbreak still wouldn't work. But cidya & all the other apps I got from cidya were still on my phone. I re jail broke it today & now it won't get off of safe mode.
