Can I use Chinese version of iPhone in US, Verizon? Other than two chips, is there other problem?

No, you can't. There are fundamental differences in the iOS version that is installed on phones intended for sale in China. Verizon's system will not recognize or activate them. I tried more than once when I worked for them.
