I'm able to run the O'Reilly iPhone book apps in fullscreen native iPad mode. Steps: use Spirit to jailbreak the iPad. Use Cydia to install JB app FullForce. In Settings -> FullForce, turn the switches for the desired book apps. Then run a book app. The apps work perfectly!Can view much larger chunks of text now. Very few apps work well with FullForce. Tweetie 2 is the only other app that I have found which works well with FullForce. You app developers did a great job.
Note: Don't take jailbraking lightly. Read up on its risks and possible issues. Read about it a second and third time. If you proceed, do it yourself to better understand the process.
