Problem Encountered :

I am experiencing this particular problem which is my iPhone4 connected USB cable and connect it to my iPhone compatible device for music it keeps skipping or it sounds like it is disconnect and connect disconnect and connect but i don't think it is disconnecting since the iphone is charging without interruption at all. I thought it was the device so i tried with my iPhone2g and iPhone3GS and both works without any problem at all. I tried with iPod and it is ok as well. The only thing i didn't try is using another person's iPhone4 and plug it in.

Have you all experience this before? Is my iPhone4 defective!?
