Besides apps like Trapster, the other big program everyone is waiting for is ShapeService's IM+ which we know is in the works. We heard January/February, then April and here we are in May and still nothing yet. Well, good news is we're almost there.
Dear WP7 users! Thank you so much for your interest to be the first to try IM+ on WP7 platform!
We're sorry for the delay, the development for this platform takes a bit longer than we expected. Anyway, good news for today: the beta testing will be public. However due to technical restrictions you will need the Developer' phone to participate in beta testing. More details on beta will be announced next week
So good news for us with dev devices as it looks like we'll be able to join the pre-party. The bad news is it's still in development, which means we're at least 30-60 days off from Marketplace release. But hey, at least it still exists!
