When i try to jailbreak my 3g iphone (on 2.0.2) with winpwn 2.5 i get a strange error. It says something about "Data Execution Prevention" has stoped the task. Has anyone ever encountered this problem? I tried to turn off the data execution prevention using this guide (http://www.realtime-vista.com/administration/2007/04/disabling_data_execution_preve.htm) and everything seemed to work but when i tried to pwn the phone again i got the same error. Any help would be much appreciated.
