Today my OS (win XP) crashed and i had to reinstall from zero. After i have reinstalled all i have this huge problem. All my pictures contacts and apps are ONLY in my 3G 8GB iPhone. What i want is to back up all to iTunes again but if i try to sync iPhone i get the message that the phone is already synced with another iTunes so if i do sync i lose everything. How can i keep my contacts and photos???? Where are stored and if i copy that files and then sync can i put them after again in the phone???? Swap tunes can help me???????
