Adobe Flex: debug data synchronization problem

I've written a small adobe flex application that allows people to broadcast short messages to their friends and family who are also using the application (kind of like twitter, but less public, and with more characters available for each message). The application uses a combination of adobe flex, amfphp, and a mysql database. So here's the story. I'm new to flex, and the application's got a bug that's driving me insane. It's time to call in a pro... I'd like the software to work offline, that is I'd like to queue up a message for when internet connectivity is available again, and received messages that were missed when I was offline). I've written code for synchronizing locally stored data with a master copy stored remotely, but the software's got a bug where the synchronization isn't always working right. There are two options to fix the problem. 1. you find and fix this bug (probably rewrite the synchronization code) 2. you get the software to work with Adobe LCDS (I was never succesful here either and gave up, trying to write my own synchronization code)
