Non-Iphone headsets on Android phones
This is general issue, IPhone headsets have the pins for mic/ground switched, so that 'standard' headsets will not work. This is done so that Steve Jobs/Apple can make more money
All you need is a pin-converter cable. I found this one which makes any non-Iphone phone accept IPhone headsets etc.

iPhone Headset to other Cell Phone Headset Jack Adapter - 3.5mm 4 conductor TRRS Male to Female
Its pricey but well worth it if you don't want to buy an IPhone and make Steve rich
