Wall AC Charger USB Sync Data Cable for iPhone 4, 3GS, and iPod
Hi.  I bought this regardless of the reviews.  I don't see what the fuss is about.  It works fine and charges the phone.  By morning, I have 100% regardless if I am using a $50 charger or a $3 charger.  I literally bought a pair of Apple headphones and this charger from 3rd party, regardless of the negative reviews, work just like regular Apple iphones and an Apple charger.  I think Apple loyalists are on this giving it bad reviews.  It works fine.  Five stars.
