iBooks coming for iPhone?
I downloaded it and peeked inside; it looks like it to me ... eventually.
If you use the grid view in your Apps section of iTunes 9.1, you can see which apps are just for the iPad, just for iPhone/iPod touch, and which are for all three via universal binaries.
Using that info to find a universal binary app I already owned for comparison, I also peeked inside DropZap.
After unziping the .ipa files and looking in their .app package contents, I took a quick look at the executable files (named iBook and DropZap respectively) with the 'file' command from a terminal window.
What I found was that both of them are Mach-O universal binaries with 2 architectures: armv6 and armv7.
But iBooks doesn't present itself as an app for iPhones and iPod touches in iTunes, so I'd suppose Apple is waiting to release it for those platforms. UI tweaks maybe?
To me, iBooks is one of the most interesting apps for the iPad. How well it works will be a large factor in my deciding whether or not to get a dedicated eBook reader such as the Kindle. Working on the iPhone as well would just be more points in its favor.
What do you guys think?
