I ordered this dock connector for I had problems on my iphone 4s, I change myself through a video-phone DIY and removal kit (JK-101 6 in 1 Disassembly Kit T5 opening pendagonale for repair) also available on amazon and of good quality, in short, I got my dock quickly it arrived in appropriate containers and more blocks to the Speaker was provided bonus while walking again and at lower prices ... PS: for experienced like me who want to change themselves parts of their Iphone I suggest you wield as much parts as tools carefully.
