Release of Android 4.1 Jelly Bean has put Developers in fast track mode and related stuff has started to roll out slowly. Few hours back, we talked about flashing the Jelly Bean ROM on Galaxy Nexus device. Now, you can install the new Google Play store on any android device thanks to the APK released by XDA forum member imbonez9.You can just download the APK and install the updated Google Play store on your Android Device.
Download Jelly Bean Play Store here.
We tested it on our low end Android Device LG P500 and it got installed without any issues. We checked the Play Store version and it turned out to be 3.7.11.
Keep in mind, if you are out of US and still install the APK, you wont notice anything new from the existing Google Play Store as most of the new features of Jelly Bean are only available in US only.
