content: I tried it with my iPhone 3Gs and it worked fine. But when I tried it on my iPad, iTunes 10 never recognized my device. As soon as I tried the original Apple cable, it recognized it successfully, I tried the retractable cable again and iTunes went back to not detecting my iPad.I tried another cable from Amazon (Apple iPhone 3G Retractable Sync & Charge USB Cable (White)) and it passed the test successfully. I recommend it for users who own both an iPhone and an iPad.
