Google posts Android 4.1 Jelly Bean images for Nexus devices
 

If you're the sort to get a little too adventurous with CyanogenMod 10 or other custom ROMs, Google just gave you a crutch. Android 4.1.1 factory images are now available for every Nexus device that can currently get a taste of Jelly Bean: the HSPA+ Galaxy Nexus, Nexus S and the expected Nexus 7. While it's not a complete safety net, the gesture will let dedicated modders flash their phones and tablets knowing that they can almost always jump back to the pure OS if someone's definition of "alpha build" is a little too rough. CDMA users are unfortunately left out of the loop; let's just hope they're brought up to speed before too long.
