Most often it is due to a poorly written app or apps. Or a conflict with the home replacement used (Timescape).
Check what the scenario is leading up to the FC (Force Close). What apps are running at the time etc. Sometimes, uninstalling all your apps, and then reintroducing them one at a time to see if they are causing the issue can often find the problem app.
Or, try asking in the Apps thread if any of the apps you have installed are known to cause issues.
