Looks like it's time to get acquainted with the
Meta-Doctor. Verizon hasn't officially blessed 2.2.4 for the Pre 2, but, once you get the Meta-Doctor set up, there are trivial
scripts you can run with it to pretty much create your own. Since you don't plan on activating it yet, I'd say go with
Code:
| ./scripts/test-verizon-pre2-2.2.4 --wifi-only | |
Since the upgrade is only as permanent as you want it to be, you can go back to 2.1.0 whenever you feel like it, either by running the Verizon 2.1.0 Doctor or using Meta-Doctor, such as
Code:
| ./scripts/test-verizon-2.1.0 --wifi-only | |
I'm recommending the "--wifi-only" flag on those because it bypasses carrier activation and lets you get a Palm Profile (er, "HP webOS Account" as it's now called) up and running by running the "Gesture Tutorial" application. Keep in mind that you'll have to run the doctor again without the "--wifi-only" flag to re-enable the cellular radio prior to activation. A combination of the Palm Profile and Save/Restore make wiping the device far from a painful process.
Once you've got a Palm Profile on there, you should have access to the app catalog. Even without that, you'll have access to
Preware. Through Preware you can overclock by installing Uberkernel and Govnah. I'm still working on getting my own Pre 2, so I'm not sure how necessary overclocking is, or how noticeable an improvement it will be.
Hope I helped. Good luck!
