I'm still a bit new to Android (just upgrading to my second Android phone now) so I was wondering, how readily can one install an unmodified "vanilla" build Android on a Verizon phone? (That would be, on a phone other than the Galaxy Nexus, which seems to have been discontinued.) Are there some Verizon-specific modifications that simply have to be included (mandatory apps, CDMA drivers, etc) or can essentially any rooted Verizon phone be used with vanilla Android? Alternatively, does anyone have any experience with alternative operating systems? I might be willing to try cyanogenmod, since apparently it offers more effective privacy controls and I've always been a bit bothered by how readily Android wants to connect to Google services.
