They have an app you can download that does this yes. While it greatly reduces the chance of it happening, it is still a possibility. My advice to you is if you plan to get CFW or HFW for the PS3, get everything you want from PSN that is for the PS3 before you install CFW or HFW. Pretty much what I have read as well. From what I gather, it seems the more times you get on, the more likely it will happen.
