Ok guys... For old bootroms and some of the iDevices you can jailbreak them using the old and well known RedSn0w. Install 4.1 and after jailbreak it using the software pointing to and old 4.0 firmware. But after the jailbreak there is a problem that hasnt been solved. The Comm Center is bugged or something like that... sooo your iDevice will be jailbroken but wont connect to internet. Will have to wait to get the Comm Center fix. Any ideas?
