As per the latest announcements made by Google, the official Jelly Bean update is set to hit our Galaxy Nexus and Nexus S devices in July. However, you can still download an image of the Android 4.1 update for your Galaxy Nexus, and can flash it right now.
The official OTA download released previously is the preview build of Android 4.1 which is meant for developers who are attending Google I/O, and will only run on devices that Google handed over to them. But thanks to an XDA member named bigxie for compiling an image of the Jelly Bean ROM which is flashable on existing GSM Galaxy Nexus devices via ClockworkMod Recovery. But remember that this is not the final build and there are quirks and bugs around the corners.
Android 4.1 Jelly Bean was announced at Google I/O and is the next big version of Android and is due to be rolled out in July for the Galaxy Nexus and the Nexus S. But if you have a handset from a manufacturer such as HTC or Samsung, then you might have to wait a tad longer before the update hits your device.
Important: Before we discuss the steps, note that although the steps to install the ROM right now are relatively simple, you got to make sure that you are rooted and have ClockworkMod Recovery installed on your device. (Here is the link for steps to get it rooted)

Here is a step-by-step tutorial on how to install Jelly Bean:
Step 1: Download and flash ClockworkMod Recovery. (Download links can be found below)
Step 2: Download the Jelly Bean image, the root fix and radio and place all the downloaded files in the root directory of your Galaxy Nexus.
Step 3: Power off your device and turn it back on while holding down the Volume Down and Power buttons and you’ll boot directly into ClockworkMod Recovery.
Step 4: Take a nandroid backup of your device.
Step 5: From the main menu of CWM, wipe your data, do a factory reset and wipe Dalvik cache.
Step 6: Now select install zip from sdcard > choose zip from sdcard > select the Jelly Bean zip you downloaded and placed in your sdcard in Step 2.
Step 7: Now repeat Step 6, but this time flash the radio file.
Step 8: Repeat Step 6 again, and this time flash the root fix. (This step is not necessary if you are not looking forward to remain rooted after the update)
Step 9: Once you’re done flashing the three files, simply select reboot system now from CWM’s main screen and you’ll boot right into Android 4.1 Jelly Bean on your GSM Galaxy Nexus.
