Probably - which storage method are you using, the MIDP Store or the persistence model? In the MIDP Store the data records are tied to the app signature (based on name/module I guess?) so during an upgrade of conflicting modules the data will be lost/orphaned. An upgrade without conflicts will keep/maintain the MIDP data intact. Uninstalling the app first (as in this case) removes the MIDP Store record(s) upon uninstall cleanly.

The bad part of persistence model is that uninstalling an app does not remove the data; in some cases that's good (i.e. you're reinstalling and want to maintain the configs) but in others it's highly undesirable (you uninstall the app and are done with it, but now you have orphaned persistence data left on the device). Also persistent data seems to be lost during a device OS upgrade, whereas with the MIDP method the data is maintained. (I have two apps that use persistence and I lose their data on every OS upgrade, booo.)
