You are right regarding some adapters. Some do change the array as i am given to believe. I haven't measured with a multimeter though. Ground would be unused in the 2.5mm pinout layout.I have a a $10 adapter from ebay and it does not change the pinout array. Buyers of adapters may want to check continiuty with a digital mulitmeter to make sure everything is on order. The ground pin is unused...
Have you checked this one out?
