Thank you for your post.
On an initial sync, the data from Bento for iPhone and Bento for Mac is merged. However, if you ever initiate a new sync, the data from Bento for Mac will overwrite the data from Bento for iPhone. However, just prior to overwriting the data on the iPhone, the information from Bento for iPhone is backed up to the Mac into a Backup folder. If you look in the folder on your Mac:
User Account -> Library -> Application Support -> Bento
You will see a "bento.bentodb" file, which is your database file for Bento 2.0v5. In addition, you should see a folder that is named after your device followed by "Backup". Do the following steps:
1. Quit Bento.
2. Rename "bento.bentodb" to "MACbento.bentodb"
3. Open the Backup folder, duplicate the most recent file, and name it "bento.bentodb"
4. Take the "bento.bentodb" file from the Backup folder and place it in the Bento folder along with "MACbento.bentodb" file.
5. Launch Bento 2.0v5, and you will see your data that used to reside in Bento for iPhone. Sync again, and the information on your mobile device will now be up to date.
If you run into any difficulty, please let me know.
In the future, since this is a FileMaker Pro forum, please post your questions to the Bento forum at http://forums.filemaker.com.
