question

First let me lay the groundwork for my question: Right now, I have one executable for both the 7" and 8.9" versions of the Kindle Fire HD. Until I get my hands on the 8.9", I won't know how well some things will work, since using a camera with the emulator doesn't really tell you how the real device will behave. I have set up the emulator to use my computer's web cam, and can actually take still pictures using the 8.9" emulator, so I have done everything I can to insure the app works properly with the 8.9. But I won't really know how it behaves on the actual 8.9" until I can get one. I preordered an 8.9" early on, but I won't get it until week after next. I will try to pick up an 8.9" in a store next week. I will thoroughly test the app once I get the physical 8.9" tablet, and make necessary adjustments. Obviously if there are issues that I discover, I will want to push out an updated binary ASAP. Now here is the question: Which will be faster to get reviewed and approved: One binary for both the 7" and the 8.9", or separate binaries for the 7" and 8.9"? If I have to make adjustments for the 8.9", can I submit just a 8.9" updated version or do I need to submit both together?
