Why can't i access my music and apps. after a restart?

[VafaTara]

Why every time i turn off my iphone (OS>2.0.2) and turning it back on, i can't access my applications and my music?
the Apps. won't open. each one of them crashes within seconds. And it seems on the iPhone's iPod i haven't got any music/video (it says: "No Content") although on iTunes i can see all the music/video i got on my iPhone and i can play them with it.
If you have some knowledge about this, please let me know. it became really irritating. it's now my 3rd day trying to find a solution.
i really appreciate any knowledgable suggestion.
By the way, i have restored the iphone many times (also as a new one)and it hasn't solve the problem and keeps coming back after every restart.
if it helps, i've runned a diagnostic test by iTunes and here is the result;

Microsoft Windows Vista Home Edition (Build 6000)

Perhaps doing a restore will help.

Re:

maybe it didnt catch your attention, but as i said before, i have restored it many times but it just won't help. it is odd. isn't it?
before this, i always thought a restore can make all the problems go away.
i suppose i was wrong!

Sorry, I misread your comment about restarting.

Was this a jailbroken iPhone? If so, that might be part of the issue.

If not, here's a link to Apples support page.

Maybe something there can help you.

Although you said you restored it, have you tried restoring it in DFU mode?

BTW, it's best not to offend someone trying to help you. Just sayin'.

Re: Why can't i access...

DFU Mode!?
No. i haven't tried it yet but i will. Got nothing to lose, i guess. I really hope this one works. Thanks for the suggestion.
BTW, it wasn't an offence. I was Just referring to my previous message.

Re: Restoring in DFU Mode

Today, i have tried many times to restore it while in DFU Mode but then i got an error message (Code error = 1600). I have a feeling that all the problems i have with my iphone is somehow caused by iTunes. Just a hunch.
i really could use someone's help with knowledge about all this. Thank you.
