The blinking cursor bug is mainly in Safari...for example if you try to log into your google account, there is no blinking cursor in the box.
The cap bug is mainly in my 3rd party apps that will have to be updated by the devs to work with 3.0. However, go into Contacts App and select the + to build a new contact. Then select name...the cap Arrow will not light up. In notes it does. So it is a bug that is in some apps but not all...just depends on what you use.
The text boxes in web pages must be rendered differently now causing all of the bugs because if you go to search in google with the top bar then you can see the cursor again.
