Smile Question regarding Xperia PLay Flex Cable

My Flex Cable just broke again and I'm planning to order the parts from China. It's only around $3 there for the OEM. However most of the descriptions say that it's a flex cable for the 4G R800i, R800x Z1i.

I was wondering if the flex cables for the non 4G and the 4G variants were just the same? Also are the suppliers from Alibaba reliable?

Thanks in advance guys! Happy New Year!
