I JAILBREAKED MY IPHONE4 VERSION 4.2.1 WITH GREEN POISON, I WENT TO DOWNLOAD THE CYDIA, MY PHONE RESET THEN COME UP THE APPLE THEM CHANGED TO THE GREEN POISON LOGO. IT COME UP WITH THE LOADING CRICLE AND THEN FROZE. I TRIED HOLDING DOWN THE ON/OFF BUTTON AND THE HOME BUTTON AND IT RESTARTS BUT AGAIN GOES TO THE SCULL AND THEN FREEZES. I HAVE ALSO TRIED RESTARTIN THE PHONE THROUGH ITUNES BUT THIS STILL DOESNT WORK. WHEN I PLUG THE CHARGER IN IT MAKES THE BLEEPING NOISE THAT IT MAKES WHEN YOU PUT IT ON CHARGE BUT THEN KEEPS REPEATING IT.

Can you restore the iPhone from iTunes to a clean 4.2.1? if you can then do it, and then run GP before doing anything else with the phone.
