For those of you wondering whether or not iBooks 2 works on the iPhone or iPod touch, the answer is yes, with a catch.

You can update your current app to iBooks 2.0, but you still cannot download textbooks without an iPad. We also advise jailbreakers to stay away from the latest iBooks update…

Considering how vast the design scope is for the textbooks, that’s fully understandable, but we thought you would like to know, that indeed, at this point it is not possible.

As far as we can tell, outside of the textbook features, there’s not any other improvements to iBooks 2 over its predecessor.

For that reason, if you have an iPhone, especially a jailbroken iPhone, we advise you to stay on your current version, because we’ve heard rumblings that it breaks the Corona update, but have yet been able to independently confirm that.

Are you disappointed that textbooks are iPad only, or do you think it makes sense?

Update: Apparently a reboot will fix the iBooks issue on a jailbroken iPhone using the latest version of Corona.
