Welcome to the forum Iylin! There are a lot of great people here willing to lend a hand anytime. Often using the Search box (at the top-left of every page) will lead you to the answers you're looking for. If not, feel free to post a question in the appropriate area.
Please take a moment to view the information here to get the most out of your iPad as well as our forum:
The answer to your question about wanting to know if Siri will be a feature on the iPad 3, no one knows and no one will probably positively know until the iPad 3 is released...likely around late Q1 2012...but that's only a guess as Apple never gives a date certain until only a few days prior.
There are already a number of discussions about this on the forum. Simply type in "iPad 3" or "Siri" in the search box at the top of the page.
Since this would be a duplicate thread, we'll go ahead and close it.
