As most Android users wait for the anticipated Android 4.2 update to hit their devices, Galaxy Nexus users will get to enjoy some of the major improvements found in core apps thanks to some leaked Android 4.2 apps. The boys at AndroidSpin managed to score a collection of GAPPs which includes the 4.2 versions of Gmail, Maps, Talk, Calendar, Clock, Photo Sphere, the latest keyboard and much more. All Galaxy Nexus users will need to do is grab and flash the zip files that are available for download using any recovery method— just like you would flash a normal ROM. One thing to note is that Google Wallet does comes as a separate .apk, so users will need to grab that separate file and sideload it if they are interested in utilizing the app as well.
