Hi guys.. i just recently purchased a iphone 3g 8gig and it had been working fine UP TILL NOW.. last night i still could listen to songs and watch movies then i realised it was too late so i left my iphone to charge while i went to bed but when i woke up, everything else was fine EXCEPT that all the songs and Vids i had were all missing! my iphone stated that i do not have any songs or Vids and asked me to head to itunes store to buy some.. but i had songs and vids last night!!! plus when i connect my iphone to my itunes, itunes states that the songs and vids are still in my iphone and so i cannot change any settings.. i tried unsnycing all my songs and snycing it back again but it doesnt work.. also i checked my iphone memory and it states that memory is taken up for the songs and Vids.. HELP ANYONE

Have you done the 3 R's?

Restart (Hold down sleep/wake button, then slide to turn off)

Reset (Hold down sleep/wake button + home button, until Apple logo appears)

Are you using firmware 2.1? This was a common issue for firmware versons below 2.1.
