how to add the start page of browser in sDK 2.0?

Used when starting the browser with a long press of “0” in the Idle state of the phone.

I'm rather sure that the default page is handled internally in the browser, and the API is not included in the public SDK. So you could try searching the open source webkit codes, or you could try Forum nokia technical support and ask them to figure it out.
