I dropped my iPhone this morning and it gave the error message "this accessory is not made to work with iphone - would you like to turn on airplane mode to reduce audio interferance? you will not be able to make or receive calls". when I called people or picked up a call, it appeared my microphone wasn't working as nobody could hear me. The iphone will not take a charge from the wall charger, in the dock or when connected through usb. The phone would not shut OFF ( it keeps restarts only). When i restart the iphone with the usb pluged in, it shows a picture of plugging the cable to itunes on the iphone screen, but my iTunes would not recognise the iphone either so I cannot restore.

Now, it wouldn't even turn on.
When i connect the iphone on the dock, the phone screen pops up "please connect to the itunes" picture but my itunes couldn't find the iphone and for about a min. then the white apple comes up and disappear over and over...

what should i do???
