HUGE iPhone 4 Jailbreak Problem

[jpderos]

All - I am new to the iPhone, so I apologize if this is an easy fix but I feel like I have tried everything.

I bought my new iPhone last Saturday 7/16/11. I was told to "jailbreak" it immediately by a buddy of mine, so I did so.

It has been working fine until today, 7/23/11. Tonight I decided that I wanted to un-jailbreak it because I saw virtually no benefits to have it jailbroken. I followed the instructions and now I am in deep trouble.

I cannot boot up the phone. I have tried the hard reset, the restore through iTunes, re-jailbreaking it. Nothing works. It gets stuck on the skull (Greenpoison)/boot screen and just freezes.

PLEASE HELP!!!!!!

Connect it to iTunes and if iTunes can recognize your iPhone then click restore and let iTunes restore.

The key to getting your phone restored, because it was already jailbroken, is to use DFU Mode. You must put your phone into DFU Mode then start iTunes and press the "restore" button. Then you should have no problems. There is a guide to DFU Mode here if you don't know how to enable it - http://www.iphoneforums.net/forum/iphone-jailbreaking-17/dfu-mode-dummies-16020/

Hope that helps.
