I figured out how to buy apps, and got Executive assistant.
It's the right idea. An app comes up while the phone is locked to display email/text/calendar/RSS notifications.
However, here are my problems with it.
First, it takes >2s to appear. It should _be_ the lock screen not show the lockscreen for 2-4s and then appear.
Second, it has no means of unlocking the phone on it. There should be a swipe thing built into it.
Third, the way to unlock the phone is to hit the home button while it is up. It didn't seem to work every time, and it seems to me that hitting the home button could easily happen by accident because you think the phone is locked.
Basically, I want Executive Assistant to appear the moment I press the wake button and be the lock screen itself. Then that would solve this complaint.
