Google I/O will be starting tomorrow and 5500 developers will come together at the highly anticipated developer conference held by Google. Google’s I/O event will also grab more eyeballs after the recent introduction of iOS6 and Microsoft’s Slate tablet and next generation of Windows Phone O.S.

Looks like someone accidentally pushed the wrong button at the Google headquarters by listing Samsung Galaxy Nexus HSPA+ as “soon the first phone with Android 4.1 Jelly Bean” on the Play Store. This puts an end to all those rumors circling around Jelly Bean and confirms that 4.1 Jelly Bean will indeed be the next Android version.

Google I/O 2012 has been completely sold out in around 20 minutes of the opening of the registration process.
