JETech® Apple USB Sync and Charging Cable Certified for iPhone 4 / 4S, iPhone 3G / 3GS, iPad 1/2/3, iPod, 2 meters (White) (Wireless Phone Accessory)
Perfect, upon its arrival I connected to iPhone 3GS and it starts to recharge, synchronization also works perfectly. It has good solid area, we'll see over time, but I recommend it!
