For Verizon Samsung Galaxy S III owners who want Jelly Bean now, there is a new option. It isn't ideal, but is better than nothing. Some devs over at XDA were able to port a TouchWiz enabled version of Jelly Bean over to the VZW SGS3. This was originally the leaked version for T-Mobile's SGS3, but has been ported over. It also has a humorous and slightly PG-13 name. It's called TouchMyBeans. Here's a link to the details, instructions and downloads below.
