Earlier this week we mentioned how the app I’m a WP7! was renamed to Outsider and re-released to the Windows Phone Marketplace. The app, made by the team at Liquid Daffodil, is for fans of Windows Phone to come together, discuss software, hangout, setup multiplayer games and just have fun. Filled with numerous Easter Eggs that include hidden functionality, the app is not only fun, it’s free.

With the update though came a challenge: Three “movers and shakers” of the Windows Phone community had to unlock 7 Easter Eggs in the app within 72 hours—if successful, Liquid Daffodil would make their other apps free for 72 hours.

Those movers and shakers were Microsoft’s Ben Lower (@benlower), Ben Rudolph (@BenthePCGuy) and yours truly (@Daniel_Rubino) and we’re pleased to announce that Lower and myself have completed the challenge with Rudolph almost finishing (he’s a busy man with a new kid, so our sympathy). As the great philosopher Meatloaf once said "Two out of three ain't bad"!

Regardless, Liquid Daffodil are making all their apps free for the next 72 hours. Those apps should be either free already for most of you or shortly becoming so when the Marketplace refreshes. Those apps are:

glƏƏk! ($1.99 US- review) – One of the most unique Twitter clients available Outsider Extras ($2.99 US) – Companion app for Outsider gives even more features Add to Contacts ($0.99 US) – Search for contact info using Bing and save to your People Hub Calendar Search ($0.99 US) – Search your calendar for past and future events

We regularly use all the above apps and they’re top notch--not only are they well designed but those bottom two are super useful as they fill in gaps in the Windows Phone OS. You would be crazy to not get these apps and save yourself $7.

A big thanks to Liquid Daffodil for offering up their software for free and supporting the Windows Phone community. Remember, this deal is only active for 72 hours so go get them now because once you lock in that “free” license, it’s free forever.
