What you need to do is edit your build.prop file. PLEASE MAKE A NANDROID BACKUP FIRST!!
Use a root file browser/editor (Like ES File Explorer) go to /system and open the build.prop file
edit these lines... (WITHOUT QUOTES!)
Ro.product.model change to "galaxy nexus"
Ro.product. brand. Change to "Google"
Now Restart The Phone
You might be able to operate sphere panorama now!
Thanks to FatherD and aniket.sananse over at XDA for this tip (Find the Thread Here)
Warning! This might not work, as it is for a different device, and I have not tested it yet, as I am not on Jelly Bean (Yet!).
Please make a Nandroid Backup!
To do this you need to boot to CWM recovery with POWER + Volume Up -> press Volume down until you get to backup and restore -> Press the Home Button -> Make sure you are on Backup -> Press the Home Button, and then wait!
EDIT: My bad about the link, I was using IE and it always shortens links I copy and paste. Sorry, I am now using chrome and the links changed.
