say I disabled some of the moto and verizon bloatware apps but through the settings>apps menu would this cause errors when I revert back to ICS? I'm guessing no.
If you were on a leaked version of ICS such as .214 or .215 and reverted back to stock ICS .211, it shouldn't cause errors. Now if you were on stock ICS and you froze or uninstall, it may cause an error if an update to JB is pushed or if you manually install it. If you disable it, you should be OK since it is still there on you phone...however, I've always reverted back to stock before any update and so this is really a guess.
