Well, this is both cool news and disappointing. It's cool because a new and improved Ice Cream Sandwich ROM (I535VRALHD) leaked for the Verizon version of the Samsung Galaxy Nexus. It's disappointing because a Jelly Bean ROM it is not. What is especially disappointing is that while Verizon is still durdling around with ICS for their SGS3, other carriers like Sprint have leaked versions of Jelly Bean already.
Still, we probably shouldn't look a gifthorse in the mouth and improvements are better than nothing. You can find detailed instructions and download links at the source link below. If you decide to give this ROM a try, remember that it will wipe all your user data. Also, come tell us about it after you try it out.
