There is a DeveloperDeveloperDeveloper community event scheduled for 7th October 2010 in Manchester, for Windows Phone 7.
As well as hosting some great talks they are holding a “XAPathon”, which basically means an oppurtunity to get your WP7 app onto a real device! In their words
if you have been working with the Windows Phone 7 developer tools but haven’t been able to run it on a real phone yet, compile it with the RTM dev tools and bring along your XAP and we’ll be providing some real phones you can try it out on
The DDD days are ran by the community and have historically had some great speakers. Get yourself along especially of you have a cool app you want to try out.
