Instagram showed an early version of their upcoming Google Android app at the ongoing SXSW conference in Austin, Texas.
The company even went on to claim that in some manners, the Android app would be better than their iPhone app.
Though this sounds more like a marketing mumbo jumbo to get more Android people to use their app when it is launched.
In any case, Instagram is hugely awaited on the Android platform. Most people look at it as a photo sharing service. Android has tons of them including PicPlz and Lightbox. But Instagram is huge amongst the iOS user base and would let you socialize with your friends using this app finally.
