First of all thanks Pali, sublime work! It works very well

Ok guys I wanna ask you a question that's been haunting me for weeks
Everyone knows that the enhaced open standard profile that iPods and almost every cellphone nowadays use for 3,5'' jack isn't actually bundled into the Maemo ecosystem, so you can't control the cellphone by wired remote neither talk by wired hands-free. Is this a software problem, that could be patched? Or is this a hardware limitation? If the first answer is yes, could this be patchable in a kernel release?
