Charging issues at home, not in car

[hwudoin]

Maybe someone here can help or exlpain what may be happening with my phone. If I charge it in my car it chrges just fine, but not at home. I have tried the wall charger and the cradle at my computer, but most of the time it won’t charge. I thought it could have been the chargers or cords, but it charges my wife’s iPhone just fine. This makes things hard because it won’t sync with iTunes when I plug it into my computer. It has worked a couple of times, but mostly not. This all started last week after months of no trouble at all. Any ideas?
