Well I have lived in China for years and I have never seen a phone in China that needs to be unlocked. The only locked phones in China are phones made only for China. Most of the phones are copies, real or copied skins with hacked software or something to that effect. If you can't find a single for your phones it is because they sent you phones not made for the usa signal or just junk phones which is probable. You have to get your phones from either Guangzhou or Shanghai. Anything coming from Putian province is junk and horribely fake. Most things coming out of HK are made in Guangzhou or Shenzhen. I would double check the phones before buying anymore. You can get good V3s in China for around 110 or so.
