First of all, it's rather an odd date for Verizon to update the Thunderbolt firmware, don't you think?
Secondly, I have had nothing but bugs since I did the update and am a bit perturbed by the fact that Verizon has released this. It appears to me they released it only for their benefit and not the users. They now added a message when tethering the computer to a laptop saying basically you're an idiot if you think you are going to get this free. They also added that to the hotspot feature.
As far as fixes, from their summary, they said they fixed something about the weather widget, well mine doesn't update correctly now when it should and it did before the update. I have to remove the widget then add it to get the weather to update for my current location. They broke it, not fixed it.
Internet connection mode: worked great before. Now it not only give's me their nag message about having to pay when the promotion is done but the phone internet goes down when I've disconnected the USB cable and won't come back up until I cycle the power on the phone. Hey, it use to work flawlessly and now it's buggy.
So my conclusion is a) the only reason for this latest up date is about Verizon and not about the customer. b) Verizon has no regard for their customers and rather release a shoddy firmware update that has more problems then the original only to update their revenue base.
