It wasn’t very long ago when the only way to experience the benefits of Google's latest mobile OS, otherwise known as Froyo, was to own a Nexus One. For months, N1 owners enjoyed the new features that came with the OS like the JIT compiler and Flash while others watched in envy. The next phone to receive the much anticipated update was the HTC EVO 4G. Now according to Android Developers, Froyo is finally starting to spread and has reached as many as 28.7% of all Android phones, with 2.1 taking the biggest piece of pie at 41.7%.
