The CA-42 “Nokia” cellphone data cable was shown to be a good start for an Arduino cable conversion. Recognizable IC’s with part numbers screened on. Piece of cake! Search eBay for “CA-42” and you’ll find tons. Beware the old cheap-sale-price-expensive-shipping phenomenon.
The pinout for Nokia phones is well-covered on the net, and with a continuity tester I traced back from the Nokia connector to the PCB.
