Nokia has tweeted an image of two Lumia 1020 smartphones, with one of them running Instagram for Windows Phone. Nokia, however, hasn't provided any date of availability for the app, but just says it's “coming soon”.

Like Vine, Instagram is certainly going to be a major boost to Windows Phone platform. The image sharing app for smartphone users has over 150 million users. However, Facebook-owned Instagram hasn't seemed keen on moving to Windows Phone. Interestingly, Twitter recently inadvertently disclosed Vine's availability in a blog post that intended to announce the availability of Twitter 3.0 for Windows Phone.
