If I enter a wifi password, then make a "try again" selection, the first thing I tried to enter is still populated in the text area of the "enter password" screen (great), but the cursor starts on the far left of the text area (not so great).

Instead, the cursor should start on the RIGHT-hand side (i.e. at the end of the string).  This makes it much easier to delete characters and correct previous work (using the center button to advance forward is far less intuitive than using "back" to back up and delete).

This solution will make a lot more sense when we implement soft keys, I believe...
