I would guess that all three of the ones you listed will not work, but I think you will have to do a little more research to find out the part number for the correct part. You should be able to find the information since others have found it and posted about it.
Sorry I couldn't be more helpful.
i searched and read a lot on xda...and i found a lot of people had success with i9100 flex cable on i777....just to be sure i can buy the flex on ebay that says compatible for i777 and try it...if it does not work i can contact the seller and tell him it did not match the description.
P.S there are a lot of usb flex with different code on them....rev2.2, rev2.3...2.4 etc....which one do i need?
some people posted rev2.2 did the trick while others sounded completely sure 2.2 does not work and 2.3\2.4 worked for them....who do i believe?
