Is it possible to unlock my Samsung Galaxy 3(GT-i5801)?

I moved to another country and absent-mindedly bought a SIM card for my GT-i5801 (from Orange UK) Now it's asking for a network lock code. I have searched the net and everything points to me going to a "phone" shop to unlock this, however I'm not conversant enough in the local language to understand people yet and want to carry on using my phone. Is there anyway to unlock this phone? Either that or I have to wait a month until I can get back to the UK.
