Device ready is not fired in IOS after receiving a 302 temporary redirect from remote server

We build a hybrid iOS app to load remote web pages using Phonegap, and meet this issue while upgrading to 2.5 from 2.4.

There's a sample page to show this：
http://dev.videgree.com/RusliTest/App/

We alert some messages after device ready in both 2 pages.

The server will be response a 302 temporary redirect after we posting the form in the First page.

And the Second page will finish loading without onDeviceReady, only a dom ready.

It seems that native webview won't fire a onNativeReady after getting a 302 response on Phonegap 2.5?

Thanks for any help.
