I saw this charger being sold on Amazon at $1.71. A price so cheap it’s ridiculous. I guess the supplier is overstocked big time on this part. What with iPhone 4S on sales and all, an iPhone 4 only charger cannot be flying off the shelf. I’ve never used this particular no name, generic charger before but all I’ve ever used are no name, generic chargers and they all worked fine. So I guess this one is good enough and it might even work for iPhone 3G or 3GS too. If you ever wanted a car charger for your iPhone, grab this now before it’s all gone. The Car Charger for Apple iPhone 4 (Black) Not compatible with iphone 4s is available from Amazon.
