So, my mobile is 6131, i bought this cable by 0.16$ and the shipment by 4.86$ crazy huh, why i give 4 stars, just to be fair enough, the cable is good, you can do almost every thing, fast transfer for files, connecting to the internet (in case you have GRPS activated from the network provider) and data and synchronise and so on, which all i was doing fine with the Bluetooth, slower but fine,why i bought this cable, to be able to update the firmware from 5.5 to 6.1 and i was wrong and the operation fail in the middle of the update and the mobile shutdown half uploaded and died, there was no other way but going to NOKIA and ask them to fix it and i paid fortune,so if you don't look for firmware you can buy this cable and you will be extremely happy, it is 0.16 but never buy it for a firmware update, please please please
