Got my new iPhone 4s earlier this week. For some reason whenever I restore the 4s from my 3gs backup (running IOS 4.2.1), it won't sync and I get an error saying my iphone can't sync because the sync session failed to start. I restored my 4s and am able to sync just fine after a fresh restore, but once a restore from my 3gs backup - it fails to sync again. I am running iTunes on Windows 7, however I have tried syncing on my sisters macbook pro and get the same error. She has a 4s too and hasn't had this problem though.


Any help would be greatly appreciated.

    I Have an Iphone 4 and just updated to ios5. 

    Ever since doing this, I cannot sync my phone either.  I triple checked to make sure that I Wasn't out of room on my phone and that was not the case.

    I tried to do a system backup and that will not work, even if I go that route, Apple is holding me hostage for previous purchases that it says have not been backed up yet will be lost and I will need to repurchase.

    So, I cannot back up phone and restore because I will have to rebuy apps, songs, etc,

    I checked my Ipad2 which was updated to IOS5 and the music is on there.

    I am afraid to try and sync that aswell to see what I may lose.


    Does anyone know a fix for this?  All is want to do is to be able to sync my iphone...........I am hoping that this is a simple setting that needs to be adjusted.    PLEASE PLEASE PLASE help.
