First the good news: Flory is a free instant messaging app that supports Google Talk, has push notifications and a live tile. On top of all of that, it completely works, allowing you to be signed in and receive messages "in the background". Huzzah!
Now the bad news: It's in German and therefore only in the German Marketplace for Windows Phone. [Update: Flory is coming to the US Market very soon. See here for more info]
Yes folks, those crafty Germans have had this app for awhile unknown to us while we patiently wait for IM+. We've been running it for the last day and it's behaved like a champ. Sure, the menus are in German but you can still finagle your way through the logins. The app works through a service called Flory, which then enables you to login to Google Talk. Incoming IMs are pushed to the device via Toast Notifications (the ones at the top) and/or the Live tile. The delay is no more than that of an SMS message, that is, it's fast and has been very reliable for us.
So how do you get this on your phone? We'll go over three options after the break...in the meantime, check out the video hands on.
