Can I update my jailbroken phone to 4.0?

*ignore please, posted in the wrong forum...sorry*

Hey All,

I can't seem to find a clear answer on this. Will I run into any problems if I just connect my phone to itunes and update to 4.0? I know I will lose my jailbreak and that's fine with me, but will it brick my phone? Do I need to backup first?

Thanks guys

Yes, you can, using 9.2 itunes only; you'll loose the jb. It is also recommended to back it up
