I am about to convert my iPhone OpenGL ES based app into a universal (iPhone + iPad) app, using iOS 4.2. What advice would you give me? Are there any notable pitfalls in doing so?

Make sure you get the bounds rectangle for the screen dimensions rather than hardcoding the view size or anything based on window coordinates.
[[UIScreen mainScreen] bounds];
Recognize that if your application wasn’t fill-limited (i.e. the hardware can only fetch so many texels and display so many fragments per second) on the iPhone 3GS or earlier (640×480) screen. That it very well may be fill limited on iPad or iPhone 4 (1024×768 or 960×640) screen size respectively.
