Details are a bit fuzzy on this right now, but developer Bil Simser has been working on an Instagram client for Windows Phone called Metrogram. Instagram is an extremely popular photo client on iOS, analogous to BubbleGum for our phones, that allows users to apply somewhat kitsch filters to their photos and share them within the Instagram network (and Twitter/Facebook). File it under "arbitrary but must-have apps" for Windows Phone.
What's interesting is how quickly Simser coded the app, once again demonstrating how easy it is to write apps for Windows Phone. According to his Tweets, it did not take very long at all:
"58 minutes later an a new wp7 Instagram client is born. I think that's a record for me" "Writing the Instagram client for #wp7 has been so freaking easy. 2 hours and I have a fully functional client"
By the sound of it, this isn't just a viewer of Instagram photos but rather something to create photos with directly. However, we're not sure if this is official (and Simser was hired as a contractor) or this is just a side project. Looking at the name Metrogram, we're betting unofficial. We've reached out to Simser to hopefully find out more info, so until then, just relish those screenshots.
Update: Developer M.Saleh Esmaeili chimes in that this is just a viewer-only, as Instagram APIs restrict access (though some sites do interact with Instagram). Hopefully we'll hear from the developer soon.
