Welcome to the club.
I've been trying to deal with apple on this issue since I first posted this thread, with no further luck. They keep wanting me to try upgrading to 4.2.1 again, to see if it'll work, but the problem is I won't be able to downgrade again(this apple employee didn't know that apple unsigns dated FW's after a week or so. He said to try creating a new user on your machine, blah blah etc etc
SINCE you are already screwed (sorry, I do feel for you), I was wondering I'd you could try something for me. I've been reading about manually "hacking" the apple backup to including the SMS history. If I were to send you the information and walk you through the process, would you be able to try that for me? For us?![]()
Manually hacking the apple backup doesn't work. I tried it. I presume you are talking about replacing the file with the SMSs wiped off in the backup with one containing the info. iTunes doesn't put that back on the phone. Apparently every file is marked for that particular backup and the files not belonging to it got ignored.
Apparently the "iPhone explorer" software is able to take data off and put data on the iphone. However, to access text messages you'd need to jailbreak the phone (I had my 3G jailbroken to use it on a different network but have no intention to do it now)
I'm still to try and restore my backup to a phone running 4.2.1 (obviously a spare one). I might get some time for this over the Christmas break. You could use your work phone to try this?
