i hope this will help here .. around $5 for x3 replacement n900 stylus http://cgi.ebay.com/3-x-Replacement-...item20b060e256 http://cgi.ebay.com/3-x-Brand-New-St...item19bbcaa055
So.. did you ever try to find one, or simply came round here counting that someone will give you a straight answer on a golden plate? I was trying to find a genuine replacement too, yet I did pretty hefty googling beforehand and got here to this very topic only to quickly go through it and see that nobody have actually got a genuine replacement in hand - without asking generic and useless questions like 'where do I get one from?'.
