It's still some months off, but some people, somewhere, are working hard on the next big leap for Android, codenamed Gingerbread, but more commonly-known as Android 3.0. The Phandroid site has managed to get initial details, which offer an interesting first glimpse into that next generation.According to TechRadar, Phandroid has got exclusive details from its 'trusted source' at Google, claiming the operating system will be going through a graphical change, with green being the new colour of choice. Google itself seems to be more prominent, with Google's own app being integrated into the operating system as extensions rather than simply being apps or accessories. Also on the Google front, YouTube is being given a makeover for the new OS too.There is also said to be better Google Voice and Google Talk integration, while new animations are being added to icons and overall, work is being undertaken to make it a 'cleaner, more uniformed' operating system.Early 2011 is the estimated date of arrival, so still plenty of time for things to change before then. But if it develops as planned, we could finally see the 'Google phone' we were promised all those months back.
