Im confused. My iPhone, OOTB 1.1.3. I had made a downgrade to 1.1.1 and jailbreaked it. Then I upgrade to 1.1.2. All seems perfect. But every time when I try to jailbreak, (jailbreak.jar with OS X with an iMac, or windows.bat with XP Parallels on MacBook) I got the message: "Cannot connect to your device: please plug your iPod/iPhone into your computer..." Whats wrong?
