Hi. I downloaded the app titled WM Live, which basically is the beginnings to integrate XBox Live with Windows Mobile devices. The software is a fantastic beginning, and i saw one other app which seems to have the same basic idea but less info.
I did have a suggestion or two. I would like to see in the future release to be able to send invitations/messages to other Xbox live users (your friends list), also be able to log into your own account to search and queue up downloads to be ready for you when you turn on your xbox and log into Live from the marketplace. Not sure of the latter suggestion will work, but its just out of mere frustration that Microsoft hasn't done anything to tie up the devices/services together.
Of course i am sure this will all be possible for future updates and such. This a great beginning and i am happy to see that finally developers are taking it into their own hands to figure out how to integrate the fine services Microsoft offers. I still can't believe that Microsoft has not even released native apps or natively integrated XBox live or Zune features yet. I am sure with WM 7 being released in 2010 we will see all of that and then some. I dont own a 360 nor do i have an Xbox live account, but i installed this app so i can just say i have the capabilities.
