One of the big moments in Windows Phone Mango diary is the debut of Nokia's first Windows Phone. Widely expected to be announced at the Nokia World conference on Oct 26 and 27 in London, the Nokia Connects blog is offering the chance to win a trip to the London ExCeL centre for a lucky reader.

What you need to do is write a short blog post (around 200 words) or a video (up to two minutes), and either leave a link in the comments or post it in Twitter to @Nokia_Connects and include the #NokiaWorld hashtag. You've got until midnight GMT on Tuesday night to get your thoughts online.
