I order products directly from China to resell in the USA. It comes as little surprise to me why more don't do this.
China: I have confirmed that the 5310 can not used in America.
Me: Do you have another phone similar to 5310?
China: There are 5310 BT and 5310 for your choice.
What!? We JUST said the 5310 was NOT for USA. I then ask for a USA phone, and you recommend 5310. Your killing me.
