Today, I just update my iPhone 3g to ver.3.1.2
Once it done, when i try to sync with itunes, it prompted out "error 13001" and i find all musics and videos unable playing. ( the applications still working )

Out of ideas, i update itunes to latest version and trying resync again.But it doesn't help!

Next, i try to restore my iPhone but it doesn't help neither.....

Later, i find out all my contacts and sms is gone too. ( i thought restore only for phone setting and it doesn't delete anything)


Q1. Any idea to clear error 13001 so that my iPhone able sync with itunes ?

Q2. Any chance i able to retrieve back my contacts list ?
