I previously jailbroke my iPhone 4 and it is now running very slow, probably due to all the jailbreak stuff. Therefore when I get my iPhone 4S tomorrow, I would like to set it up as a new phone and not restore as backup. The only thing I need in terms of data from my iPhone 4 is my SMS/MMS history. Since the iPhone 4 is jailbroken I SSH'd into it and got all the info I need, but I'm not planning to jailbreak the iPhone 4S so I'm not sure how I could put it back on the new phone. I also pinpointed the hex file in the iPhone backup that stores all the SMS data, but when I tried to replace that with the same file on an iOS 5 backup, iTunes returned a 'backup corrupt' error. (Even if this did work I'm fairly sure it's only the SMS and not the MMS, since the file I found is only 8MB.) Any help would be greatly appreciated.
