my iphone 4 has been jailbroken using absinthe 2.0 and worked very well for a few months. recently it has been rejected by itunes. i got a new MBP and now when I attach my iphone to the MBP itunes gives the following error, "iTunes could not connect to this iPhone. A secure connection could not be established."

I have restarted the phone and computer. reinstalled itunes on the laptop. updated everything i can think of. i am currently backing up my iphone to the icloud system. if anyone has any ideas that don't involve wiping it clean and starting over I'd love to hear them. Thanks in advance!
