I am currently using an iPhone 4 with iOS 4.3 and the battery of my iPhone will say 100% and will show the fully charged icon on the phone. On iTunes, it will say on the sidebar that the iPhone is still charging. Is my phone still charging and is this harmful to the battery? Or is this a bug with the display on iPhone or iTunes? This has been a problem ever since I got the phone in December (running 4.2.1) and still occurs.
