Getting native text input "form" directly from a canvas.

[Fraggle]

Hello,

I am wondering how we can go directly to the "native" text input panel, without using a form.
Something like canvas.startUserInput();
I have seen opera doing it with opera mini, so I'm wondering..
I want my users to be able to see a nice low level screen in my games, and when they press something - bam! directly into the phone input screen to set up their nickname.

Thanks in advance, and I hope it's clear.

Seb
