The popular photo-styling and sharing iOS app Instagram now has over one million registered users only three months after its debut, according to a post on the company's blog. The free app lets users take pictures with their device's built-in camera, style them using retro-flavored filters and upload them to popular social services. The company believes that this is "only the beginning" and has plans for a more expansive web site, more funding and an Android version of the app planned for 2011, according to an interview with TechCrunch.
