UITextField Custom Cursor?

[Darkroom]

this is a long shot, but: does anyone know of an undocumented method to change the color of the default cursor of a UITextField, or even how to override the blinking cursor image?

[Darkroom]

unfortunately, unlike cocoa, the following is both undocumented and unsupported in the iPhone SDK... for now...

[myTextField setInsertionPointColor:[UIColor whiteColor]];

perhaps 3.1 supports this? i haven't tried it yet.
