I know I'm a little late to report the news, but I wanted to have all the information available before I post this update. As some of you probably now, TheFloW has released h-encore2. This was intended to let you use HENkaku on firmware 3.71, but then Sony released 3.72 almost immediately after. Whatever 3.72 was intended for, it apparently hasn't patched up h-encore2. However, it might be forth waiting a bit before you update.

The guys at Hackinformer.com have reported that the PSTV Whitelist hack still works on 3.72. However, I cannot yet confirm whether or not the SD2Vita works on the latest firmware. And TechJames has just released a video reporting that Adrenaline doesn't work on 3.72. So if you just want to use the PSTV Whitelist hack, go ahead and update. But if you value using the SD2Vita and force-loading blacklisted PSP and PS1 games with Adrenaline, you're better off waiting until they've been updated to work on the latest firmware.
