CECT A380 IPhone Clone Change Frequency?
 

I bought three of the CECT A380 Fingerprint IPhone clones. The guy in China who sold them to me said they would work Here in the US, but they do not. Is there any way to change the frequency so it will work in the US 1900 MHZ?
It seems to only support 900/1800 but is a MT 6227 chipset as my computer recognised. I read somewhere that this chipset supports quad band, but I do ot know how to check or change it if possible.
any help would be appreciated.
Thanks

I'm in the same boat except mine was a christmas present and my dad didn't know he was buying a fake. I kinda feel bad for him so I want this phone to work so that he didn't just waste his money.
