Exception when running PhoneGap0.9.6 application on iPhone

We have an PhoneGap application that runs perfectly okay when using the simulator but once running this in the actual iPhone connected to mac we get an exception (errors below). Note the application was working perfectly fine before upgrade to PhoneGap0.9.6/

objc[356]: Class Connection is implemented in both /System/Library/PrivateFrameworks/Message.framework/Message and /var/mobile/Applications/D1D682A1-010B-4AE9-8761-4D553FCF8089/Frank151.app/Frank151. One of the two will be used. Which one is undefined.

UPDATE: After not much luck after trying many things we decided to downgrade the application to PG 0.9.5.1 and it worked with no issues. Not sure of the cause but something to do with PhoneGap 0.9.6 upgrade.

Start by disabling any plug ins......
