Okay,
1) If you are 3.52 or lower, DO NOT UPDATE, you will lose rejuvenate. Rejuvenate is a PS Vita native homebrew platform (so it can run homebrew with more CPU power than PSP homebrew).
Unfortunately, you're wrong. Rejuvenate is for firmware 3.51 and lower. You
cannot get Rejuvenate on 3.52 currently. 3.55 patched the mail hack so there is nothing on 3.55 yet.
Let me put it this way:
FW 3.51:
-
Requires a PSP game on your Vita to hack.
- Rejuvenate (native homebrew & emulators)
- PSP roms
- PSP-mode homebrew & emulators
FW 3.52:
-
Requires a PSP game on your Vita to hack.
- PSP roms
- PSP-mode homebrew & emulators
- You can wait and hope for a hack that doesn't require a PSP game (not likely).
FW 3.55 (current):
-
No hacks currently available.
- Access to PSN features
- You can purchase and download a PSP game from the store, then hope a hack comes out for FW 3.55.
If you have no intentions of buying a PS3... Either way, you're taking your chances on hoping for a hack that doesn't yet exist. Earlier firmwares were hacked due to vulnerabilities in the PSP emulation, as it is significantly harder to find an exploit that gives access to the main Vita. (Rejuvenate uses an exploit in PSM, which was removed in 3.52). For firmwares 3.52+, I wouldn't count on a method to hack without a PSP game. Hackers are going to continue to try to find exploits in 3.55 that will open up this firmware (and hopefully future ones) to the same kind of hacks we have witnessed in past firmwares. That being said, as soon as an exploit is released, Sony is quick about releasing a new firmware that patches it, so you have to react quickly once one is discovered.
