Hi all. I have iTunes 10.x running on Windows XP...my new iPhone 4S is synched with it. Unfortunately I need to restore my computer to a July backup which means 1)it will be iTunes 9.x and 2)never synched with the iPhone 4S. I do, however, have a backup of my current computer configuration (but I cannot use this backup for a full system restore)...which means that after doing a restore of July, I can go into the January 2012 backup and pull out files/folders that I need. So...I can do #1 and #2 below very easily...but is it easy for me to perform #3?: 1)Restore the July computer backup 2)Install iTunes 10.x 3)Pull out from my January 2012 backup ONLY the iTunes 10.x essentials (XML files, etc. from the Mydocuments... folder) and possibly a "backup" from when my iTunes 10.x synched with my iPhone back in December and thus have iTunes all set to go and already "knows about" my iPhone 4s or...is step 3 impossible and I will need to start all over again my registering my iPhone 4S and doing an original sync and possibly even destroying all the data on my iPhone 4S? If this is the case, can you let me know what the pitfalls will be (such as it will nuke all my iPhone data and re-copy it all which will take 4 hours, etc) I would appreciate it if your reply is specific with instructions. Thanks in advance!
