Question: I have an update to my app that has been reviewed and is **Pending Developer Release**.

I have found a bug in this version and would actually like to reject this binary and keep my existing binary.

Once I fix the bug, I would like to re-upload a new binary. Is this possible?

Answer: 
Explanation to kernix answer:

* select app in itunesconnect;
* select app version;
* you will see "You can only edit some information while your version is pending developer release. To edit all information, cancel this release." at the top of the page. Just click on "cancel this release" link.
From the [iTunes Connect Developer Guide:](http://itunesconnect.apple.com/docs/iTunesConnect_DeveloperGuide.pdf)

NOTE: You can only use the Version Release Control on app updates. It is not available for the first version of your app since you already have the ability to control when your first version goes live, using the Availability Date setting within Rights and Pricing. If you decide that you do not want to ever release a Pending Developer Release version, you will need to click the Release This Version button anyway, in order to create a new version of your app. You are not permitted to skip over an entire version.
