Wall AC Charger USB Sync Data Cable for iPhone 4, 3GS, and iPod
i purched two of these and although they do work i compared them to the the adapter and cable that came with my iphone there is a part thats not the same the end of the cord that fits in to the plug part does not go in all the way which means there is a space which could meen an electrical problem but it still seems to work.Please advise ...Irv
