Hello, I got a Telus (Canadian Carrier) refurbished iphone 4s on iOS 5.01, I jailbroken it and unlocked it using Sam, then restore it from my computer backup. However, I didn't see my old imessage info there. I thought it is just a back up problem that didn't back up my old imessage because I am using a different phone number or sth. But now I noticed that I can't view my message at all, it will show I have message, but when I open it, it shows sth. wierd like imessage(-1) and i can not see the actual message. I can even send a message using imessage, just I can't view it at all. I need help, as I understand I can't do a clean install back without going to iOS 5.1 (which will lose the ability to jailbroke and unlock).
