Wall AC Charger USB Sync Data Cable for iPhone 4, 3GS, and iPod
I wanted this to take to work for charging my phone. I was very disappointed. It is useless for the my intended purpose. While the cable works fine for charging my phone from my computer I cannot plug it into an outlet and charge because the adapter plug does not work. What you really get is a cheap cord for only charging your phone by attaching to your computer
