--------------------------------------------------------

Also reproducible for us on our Android 2.2 and 4.0.3 devices when resuming the app after
changing network state - turning off wifi or going from 3G to Edge. Can take minutes to begin
responding to touch again.  On the 2.2 phone it can even end up crashing android which reboots
or hangs until we take the battery out - this is consistent with reports from our users. This
is with Cordova 2.2.

As others have noted, when the app unfreezes, we get logs like the following:
onMessage(onNativeReady,null)
onMessage(onPageFinished,url)
There can be quite a few of these as though the app is running through a queue of blocked
events.

> When using PhoneGap 2.0.0 on ICS or JellyBean, the application freezes up after you set
the app to the background or turn of the screen. After around 3-7 seconds, the application
unfreezes and pretty much causes a panic and usually crashes. No error reports have been submitted.
> Here is how you re-produce the issue:
> 1. Download Untappd - V2.0.4(https://play.google.com/store/apps/details?id=com.untappdllc.app)
> 2. After logging in stay on the Friends tab
> 3. Turn the the screen off and wait about 3-7 minutes
> 4. Turn the screen back on, and the interface should be frozen.
> Another possible path to re-producing the issue:
> 1. Download Untappd - V2.0.4(https://play.google.com/store/apps/details?id=com.untappdllc.app)
> 2. After logging in stay on the Friends tab
> 3. Go back to the home screen then use other apps for about 3-7 minutes.
> 4. Go back into Untappd, and the interface should be frozen.
> When the app is frozen, native menu buttons will not nor any options in the UI. 
> Would love to see if anyone can replicate this. I've tested this on Jelly Bean 4.1.x
on a Samsung Galaxy Nexus, but users have been having this problem majority on ICS (4.0.x)
> Thanks,
> Greg
