It might be the problem of the firmware. If you have any problems try redoing the operation and unlock with ultrasn0w tool.

Hi there,

@ Super Marine Try using any other network and see. If you have jailbroken your iphone successfully. Then it might be some other problem.

@rue i Think it might not work some times with base band 05.11.07. Any way try after taking a backup.
