judging by what is on this ebay auction CDMA and GSM are different
FLEX CABLE+EARPIECE FOR HTC SPRINT TOUCH PRO2 T7380 - eBay (item 350396583718 end time Oct-22-10 03:32:37 PDT)
I would assume any GSM cable should work in any GSM phone and any CDMA cable will work in any CDMA phone.
I'm sure you could email them and they would tell for sure if the all the GSM cables are compatible.
