i have a xperia T that is roughly a year old and for some reason the other day i started getting the "Headset not supported. Use another headset or visit the sony support site for more information" message. i have tried both sets of sony headphones that i own and even the original sony headset that came with my phone as well as my girlfriends headphones but nothing worked at all, i found an old iphone headset and that worked but extremely quietly with the volume all the way up. i have cleaned the headphone port out just incase but again no luck at all. is there any thing that i can do or do i have to kick some sony but or even replace the port its self although i dont think it will do much.
