I had enough with waiting for the official Jelly Bean update for my phone.. And with Motorola, I can never be sure about when I will get it.. However, recently I found this 2 Holo Apps that can be used to get the Jelly Bean "look" on android phones.. This works even on the un-rooted ones (my phone is also not rooted).. Thought of sharing this for the people who are tired of waiting for the JB update.. Enjoy!
