I was able to get something going on here a couple of weeks ago:

The important bits are defining a couchbaseDidStart method:
https://github.com/alunny/ios-couch-phonegap-helloworld/blob/master/helloworld/Classes/AppDelegate.m#L125-132
and ensuring files serves from localhost can be displayed in your app
(adding to ExternalHosts in phonegap.plist)
https://github.com/alunny/ios-couch-phonegap-helloworld/blob/master/helloworld/PhoneGap.plist#L11-15
Note that mobile Couchbase doesn't include the Futon CMS as part of
its runtime - you'll need to populate a CouchDB so you have something
to display. Here's how I do that:
