I've done it. Very small, as reported. Two separate downloads. The only Widget I see that I hadn't noticed before is identified as an Android Widget, it is called "txt msg away message". It's a little 1x1 widget of the green robot either standing alert or sleeping with "zzzzz" coming from him. When you click on it, it switches between them and tells you "text away message on" or "off". I haven't tried it, but I assume when activated it responds to texts with a message that you are occupied. If you open it in applications, it gives an opportunity to input a custom away message.
It may be that this was here before and I'd missed it, but I don't think so. Apologies if I'm misreporting. I suppose it might have been installed with Android 2.3.4, and I just didn't notice it till I went looking for a new widget.
I can't tell anything about the other update, but I don't have a corporate email account on my phone, and seldom use 4G. So that may not be surprising.
Again, I'll dine on crow if this has been here for a few days and I just didn't notice it till now.
