I have been a iPhone user for the past couple of years with Windows iTunes. I recently upgraded to a 3GS and the resync did not go quite well. This leads me to ask a couple of basic questions. 1) On my windows, by default, where should I look for the sync'd data for the various applications: Stocks, weather, contacts, Clock, calendar, notes, photos, SMS Messages, Phone ( with all the recent call info as of last sync ), Mail accounts configuration etc. I have not messed with any configuration that changes the applications on my windows to which these sync to, so I suppose only the defaults would have been used. 2) Is there a Windows application that can show me all of the information that has been sync'ed back to my Windows PC in one interface instead of having to look in various places? 3) What is the difference between Backup and Sync. (I was horrified to find that the backup iTunes found was from 8 months back when I know I had connected my iPhone to my windows machine many times after that. Before swtiching to 3GS I did upgrade my 2G phone to OS 3.0 and I am almost confident that it did a backup then. ) The end result is, my 3GS is not an exact replica of the data I had on my 2G and slowly, upon discovery, I am adding one at a time. I still have not found all my old SMS messages. This basically told me I do not have a good mental model of what this whole sync and backup procedure actually does. If some can clue me in on this, that will be great. Thanks.
