Backup for pi and flexmail

[midniteslice]

i'm wondering if there is a free backup program that will backup pocket informant and flexmail that will still be usable after i flash. i've done some searching and most ppl say not to restore a full backup from sprite or spb after a new rom flash. i use the pim backup from helmi's kitchen now, but it dosn't seem to cover pi or flexmail. there are options to export data in both apps, but are they usable as backups?
lot of questions i know. appreciate the help though.
