Thank for replying.
I have been testing all 2200 3300 & 4300 for about a week and only one person reported "phone issue with IP registering"
but I did not look into it yet - I assume its not "upgrade related". I know the CPU increase a bit, and on 2200 wit 15.1R5
sensor temp did not work due to bug in software. Besides that all other look ok. I will keep an eye this week.
Thank You
