Update: For those who wants to know how it works, please read this CAREFULLY as the app might be leaking data or privacy
For Windows Phone 8 users, I know that the pain is to see your friends (on Android, iOS) posting pictures on Instagram. Do you know that you can also post those pictures and videos to Instagram too?
BTW, the app that I am talking about is NOT Instagram official app but 6tag, an Instagram client. And from my usage, it is a very good one. As you can see from the picture, the design of this app is very Windows Phone like (flat). And the fact that it can switch from picture to video means that this app actually has all the features of Instagram (except for the filter on video).
You can even have different accounts (version 1.4). So far, it has been a pleasant experience. So, what are you waiting for? Grab this free app on Windows Phone 8 now.
