There is a small maintenance update that is currently being rolled out to the fresh Samsung Infuse 4g. The update is supposed to address a small issue with email sync with Exchange 2003 servers. The OTA update is 8MB (shouldn’t take long to download). After you’ve updated, your firmware should be 2.2.1, baseband I997UCKE3, and build number FROYO.UCKE3. If you thought this was Gingerbread, unfortunately, you’ll have to wait a little longer.
