I updated to ICS yesterday afternoon, or at least I thought I did. What makes me think things did not go too well is when I go into Settings > About Phone > Software Information. I find the following: Android Version 2.3.4 and Sense Version 3.5
I also went into Settings > Software Update > Status and saw this: Name: Rezound 3.14.065.12 71ORD then Status: Update Successful.
I don't really see any changes or loss of performance since I did the upgrade and based on what others have stated in other threads I should have something even very small go wrong with the upgrade.
Did try to see if I could get rid of some of the Verizon bloatware and that could not be done.
