How do you do it? I saw one video tutorial on it, but the screen was too small. Also, other than changing the view size, are there any other major changes I would have to
XCode4:
In xcode 4 we can't do that for a single xib,but we can create respective ipad versions all at once.
Before configuring your project to ipad,when it is configured only for iphone, right click on target and click on duplicate.
Now select "duplicate and transition to ipad".A new target and new set of xibs are created.It should reduce some work.
Hope it helps.
