Iphone 3G error 24 HELP

[Partyboy2001]

I am one of 4 people I know with a 3G 16GB Iphone who after attempting to
sync as per usual are sitting with phones that are reading error 24 showing the itunes logo and USB plug.
We have tried everything suggested in various forums , Apple dont ackowledge the problem and suggest a device swap , some say its a software problem and offer suggestions to restore , however none of us have had any luck >
Please can someone help 4 very upset Iphone out of order users explain how to go about restoring our phones .
Thanks anyone who can help.:wtf::wtf::wtf:
