I'm thinking I might like to update to 3.55 to get on PSN, as well as being able to play games that require newer firmwares. The only thing holding me back is the possibility of losing the whitelist exploit. I'm using the app.db method. Reading around, it seems I'm able to create a backup of my memory card with all of the mods I want applied before updating, and should something go wrong down the line, I can restore it. Before I go ahead and do it, can anybody confirm this is indeed the case?
These are the posts I've seen sort of confirming it:
